Question

Julia correctly estimated the value of 183 ÷ (76 – 15) + 29 by rounding each number to the nearest ten. What was Julia’s estimation?

Answer 1

Answer:

2 using PEMDAS

Step-by-step explanation:

First, I would round all numbers (to the nearest tenth).

183 rounds to 180

76 rounds to 80

15 rounds to 20

29 rounds to 30.

Now plug those numbers into the equation.

180/(80-20)+30

Using PEMDAS, I solve the parentheseis first.

80-20=60.

180/60+30

Then, add 60+30.

60+30=90.

you get 180/90.

180/90=2.
