Answer:
30 ÷ (15÷2.5) + 7
Explanation:
Given: 16 · (4.5 + 3) ÷ 10= ____
First let us do PEMDAS (Parenthesis, Equation, Multiply, Divide. Add, Subtract) upon the given value.
16 · (7.5) ÷ 10 = ____
120 ÷ 10 = ____
= 12
We now understand that the given is equal to the value of 12, now we will calculate each equation with PEMDAS until we find the equivalent value.
20.8 + (3 · 4) ÷ 4 =
20.8 + 12 ÷ 4 =
20.8 + 3 =
= 23.8
24 ÷ (8 − 4) + 8.2 =
24 ÷ 4 + 8.2 =
6 + 8.2 =
= 14.2
30 ÷ (15 ÷ 2.5) + 7 =
30 ÷ 6 + 7 =
5 + 7 =
= 12
36 ÷ (9 − 4.2) + 3 =
36 ÷ 4.8 + 3 =
7.5 + 3 =
= 10. 5
It is safe to say the following:
16 · (4.5 + 3) ÷ 10 ≠ 20.8 + (3 x 4) ÷ 4
16 · (4.5 + 3) ÷ 10 ≠ 24 ÷ (8 − 4) + 8.2
16 · (4.5 + 3) ÷ 10 = 30 ÷ (15 ÷ 2.5) + 7
16 · (4.5 + 3) ÷ 10 ≠ 36 ÷ (9 − 4.2) + 3
Therefore, the answer is:
16 · (4.5 + 3) ÷ 10 = 30 ÷ (15 ÷ 2.5) + 7
Hope this helps =D, happy learning !
