8 ali shaded 0.4 of a hundreds grid. tarun shaded 0.32 of the same grid. how much of the grid did they shade in all?
number model with unknown:
answer: of the grid
explain how you got your answer.

Explanation:

Problem 1: 5 tenths + 27 hundredths

Step1: Convert to hundredths

5 tenths = $\frac{5}{10} = \frac{50}{100}$
27 hundredths = $\frac{27}{100}$

Step2: Add the fractions

$\frac{50}{100} + \frac{27}{100} = \frac{77}{100}$
Equation (in words): 50 hundredths + 27 hundredths = 77 hundredths

Problem 2: 16 hundredths + 7 tenths

Step1: Convert to hundredths

7 tenths = $\frac{7}{10} = \frac{70}{100}$
16 hundredths = $\frac{16}{100}$

Step2: Add the fractions

$\frac{16}{100} + \frac{70}{100} = \frac{86}{100}$
Equation (in words): 16 hundredths + 70 hundredths = 86 hundredths

Problem 3: $\frac{8}{100} + \frac{6}{10}$

Step1: Convert to hundredths

$\frac{6}{10} = \frac{60}{100}$

Step2: Add the fractions

$\frac{8}{100} + \frac{60}{100} = \frac{68}{100}$
Equation: $\frac{8}{100} + \frac{60}{100} = \frac{68}{100}$

Problem 4: $\frac{42}{100} + \frac{9}{10}$

Answer:

$0.72$ of the grid
