Hi! I’m stuck on this problem on math! This is 5th grade math. Can anyone help me?
emmasim [6.3K]

Answer:

The answer is 4.2 kilograms of dog food

Step-by-step explanation:

it says that ray feeds his dog 0.12 kilogram of food each day

he needs for 1 month

1 month = 31 days or 30 days

since 1 day food is 0.12 kilograms you'll have to multiply 0.12 with 1 month

i.e; 0.12*31 or 0.12*30

0.12*31=3.72 and 0.12*30=3.6

since we don't have an option we'll have to choose something bigger than this

therefore, the answer is 4.2
