x Find the product. Click for Answer

Multiply the numerator by the numerator, and denominator by denominator. Now, simplify: ÷= ×= The product is

Now try this on your own: 1. x = Show your work on the worksheet.

Find the quotient. 2 ÷ = ClickClick for the answer using a diagramusing ClickClick for the answer using the algorithm.

Convert the mixed number to an improper fraction. Then, multiply by the reciprocal of the second fraction. 2 ÷ = x= Now, multiply and simplify the fractions. x=÷== 2 Move onto the next problem.onto Go back to the problem.back To convert to an improper fraction: 1.Remember, ask yourself “how many thirds are in 2 1/3? There are 7/3s. 2.If you are not sure, draw a picture of 2 1/3, then count the thirds. 3.Multiply the denominator by the whole number, then add the numerator (3 x = 7)

Solve using a picture. Show 2 1/3. Then divide into sixths. Next, number or circle groups of 5/6. Your answer is the number of groups of 5/6 that you have numbered: 2 You only have 4 out of 5 sixths left. So you cannot make a third group. Your remainder is 4/

Find the quotient: 4.67 ÷.25 = ClickClick for the answer using the algorithm.algorithm

Find the quotient: 4.67 ÷.55 = If the divisor is a decimal, make it a whole number by moving the decimal. Then move the decimal in the dividend the same number of places. Then divide. Remember to line up the decimal point in the quotient. So, if you move the decimal 2 places to the right in.55, it becomes 55. You must then move the decimal 2 places in 4.67, to make it 467 The new problem is /55 = This is the whole number portion of your answer. This is your remainder 27/55. Now convert this fraction to a decimal. Use a calculator: 27÷ 55 =.49 Now combine the whole number with the decimal: Your answer is 8.49
