Presuming the question is "Which sum is closest to 1".
First, you need to either convert all the fractions to decimals or all the decimals to fractions, then add each pair.
0.4 + 1/2 = 0.9
7/8 + 1/4 = 1.125
4/5 + 2/3 = 1.466666...
The first one is different from 1 by 0.1. The second is different by 0.125. The third is different by 0.46666.... Therefore, the closest sum is the first, or 0.4 + 1/2
0.4 + 1/2
Answer:
3x(14)
Step-by-step explanation:
3x(7x2)
=3(14)
This is a percent proportion answer I think so you need to use the percent proportion formula and find the answer
Using the law of sins:
Sin(angle) = Opposite Leg / Hypotenuse
Sin(30) = AB /10
Solve for AB:
AB = 10 * sin(30)
AB = 10 * 1/2
AB = 5
The answer is A.
