Decimals and Fractions

Part 1: Decimals What rules do you remember?

Steps 1.Compare any TWO decimals at a time 2. fill in zeroes so that each number has the same amount of place values 3. Start at the left and compare the digits 4. Look for the first place where they are different and rank them. 5.Compare the next numbers using steps 1-4

1.Tia reported on a star for her science project that has a magnitude of Maven reported on another star that has a magnitude of Which star has the smaller magnitude? 2. It takes Pluto years to orbit the Sun, and it takes Neptune years. Which planet takes longer to orbit the Sun?

Are you Ready for Some… Dividing A Monday Morning Party…. We’ve got Ms. Evans, the PP, and your minds, Let’s get these quotients started!

Divisor Quotient Remember! Dividend Vocab Review

Recipe 1.Set up divisor and Dividend 2. Look at the Divisor, move decimal place over to make a whole number 3.However many places you moved the decimal in step 2, you move the decimal in the dividend 4. Divide as you would with a whole number

Find the quotient ÷ – 6 24 – 24 0 Place a decimal point in the quotient directly above the decimal point in the dividend. Divide as you would with whole numbers Just Watch #1

Find the quotient. 5.2 ÷ Move decimal place over once for divisor Move decimal place over once for dividend Divide – ÷ 1.3 = 4 Dividend= =Divisor

How do we add when we don’t have common denominators?!?

Fractions that represent the same value are equivalent. Remember! To add or subtract unlike fractions, first rewrite them as equivalent fractions with a common denominator.

You can use any common denominator. But it will be easier to find the least common denominator to add and subtract unlike fractions. The least common denominator (LCD) is the least common multiple of the denominators.

Time to + and -!!! Steps for unlike denominators 1.Find the LCD for the two denominators by looking for LCM 2.Make equivalent fractions by multiplying both the numerator and denominator by the same number (to get LCD) 3. Add the numerators, leave your denominator 4.If needed, simplify

11 12 __ 3 8 – __ 3 8 – __ 9 24 __ Multiples of 8: 8, 16, 24, … The LCD is 24. Write equivalent fractions with a common denominator. Subtract __ Multiples of 12: 12, 24, …

4 7 __ 1 3 – – __ 7 21 __ Multiples of 3: 3, 6, 9, 12, 15, 18, 21, … The LCD is 21. Write equivalent fractions. Subtract __ Multiples of 7: 7, 14, 21, …

What did CL do wrong?

Add or subtract. Write each answer in simplest form – 3. – Bonnie is making oatmeal bars and the recipes calls for cup of brown sugar. If she has cup of brown sugar, how much more does she need? 3 8 __ __ __ __ 5 12 __ cup

How do we add and subtract Mixed numbers?

2 3 __ __ The LCD of 3 and 12 is 12. –1 1 4 __ – __ ______ Write equivalent fractions with a denominator of __ Subtract the fractions and then the whole numbers. 5 – 1

1 2 __ __ The LCD of 2 and 7 is 14. –1 3 7 __ – __ ______ Write equivalent fractions with a denominator of __ Subtract the fractions and then the whole numbers. 4 – 1

Renaming fractions I need to rename to have enough fourths to take away from Here’s how you do it! 1.Subtract 1 from your big 2. add your numerator to your denominator 3.Answer to step 2 is your new numerator

Lace up your shoes and let’s get ready to PRACTICE!!!!!!

1 6 __ Rename 7 as = –2 5 6 __ –2 5 6 __ ______ __ Subtract the fractions and then the whole numbers. 1 6 __ Write the answer in simplest form. = __ 7 – 2

2 5 __ 7 10 __ __ __ Rename 8 as = – __ – __ ______ ______ __ Subtract the fractions and then the whole numbers __ 4 10 __ 10 __ 4 10 __ 10 is a multiple of 5, so 10 is a common denominator. 8 – 6

Summary In your groups, fill in the blanks If I go to subtract my fractions and there isn’t a large enough fraction to subtract from I must ____________one of my fractions. To do this I subtract 1 from my _____________ number. Next, I __________my numerator and denominator, this is my new ____________________. This whole process is called _______________________________.
