Statement Sums Involving Decimals
Statement Sums Involving Decimals
Statement sums involving decimals:
Example 1: If 58 out of 100 students in a school are boys, then write a decimal for the part of the school that consists of boys.
Solution: We can write a fraction and a decimal for the part of the school that consists of boys.
Example 2: Melissa purchased $39.46 in groceries at a store. The cashier gave her $1.46 in change from a $50 bill. Melissa gave the cashier an angry look. What did the cashier do wrong?
Solution: We need to estimate the difference to see if the cashier made a mistake.
$50.00 - $40.00 = $10.00
Estimate: $1.46 is much smaller than the estimated difference of $10.00. So the cashier must have given Melissa the wrong change.
