Yes! Always simplify the numerator and denominator separately before dividing. So calculate 0.18 + 0.37 = 0.55, then work on the denominator: 89 + 13 - 2 = 100.
When dividing a decimal by 100, move the decimal point two places to the left. So 0.55 ÷ 100 = 0.0055.
Absolutely! Just make sure to follow the order of operations. Calculate the top (0.18 + 0.37), then the bottom (89 + 13 - 2), then divide the results.
Double-check your arithmetic! The most common errors are: forgetting that , or making calculation mistakes in 89 + 13 - 2 = 100.
