Math Problem Statement

Solve the following problems: a) 29 × 0.2 b) 142 × 0.3 c) 76 × 0.7

Solution

I see the image contains three multiplication problems:

a) 29×0.229 \times 0.2

b) 142×0.3142 \times 0.3

c) 76×0.776 \times 0.7

Let's solve these step by step:

a) 29×0.229 \times 0.2

29×0.2=5.829 \times 0.2 = 5.8

b) 142×0.3142 \times 0.3

142×0.3=42.6142 \times 0.3 = 42.6

c) 76×0.776 \times 0.7

76×0.7=53.276 \times 0.7 = 53.2
