Write the following decimals as a fraction: 1).152).2363).4915 Write the following fractions as a decimal: 1) 153/999 2) 23/993) 461/9999

Solve: ̶ 2 + ( ̶ 4) Look at the signs directly in front of each number. Same Signs… ADD the numbers. KEEP the sign. Different Signs… SUBTRACT the numbers. Give sign of the bigger digit. Same Signs ADD the numbers. KEEP the sign. 6 ̶ 6 ̶ 6

Solve: ̶ Look at the signs directly in front of each number. Same Signs… ADD the numbers. KEEP the sign. Different Signs… SUBTRACT the numbers. Give sign of the bigger digit. Different Signs SUBTRACT the numbers. Give sign of the bigger digit. (An 11 is bigger than a 7. The 11 is positive, so my answer will be positive.) 4 4

̶ 51 + ( ̶ 19) ̶ ( ̶ 30) Same Signs Add the digits and Keep the sign. Different Signs Subtract the digits and give sign of the bigger digit.

̶ 63 + ( ̶ 20) ( ̶ 105) ̶ Same Signs Add the digits and Keep the sign. Different Signs Subtract the digits and give sign of the bigger digit.
