Question

mrs. smith asked her students to write a group of equilvalent numbers. the responses from four of her students are shown: 207%, 2 2/10, 2.0715/5, 2.4, 24%2.125, 212.5%, 2 1/82.02, 101/50, 202%which ones are correct?

Answer 1

Verify each student

N 1 207%, 2 2/10, 2.07

207%=207/100=2.07

2 2 /10=2+2/10=22/10=2.2

2.2 is not equal to 2.07

The N 1 is incorrect

N 2 15/5, 2.4, 24%

24%=24/100=0.24

0.24 is not equal to 2.4

The N 2 is incorrect

N 3 2.125, 212.5%, 2 1/8

212.5%=212.5/100=2.125

2 1/8=2+1/8=17/8=2.125

The N 3 is correct

N 4 2.02, 101/50, 202%

202%=202/100=2.02

101/50=2.02

The N 4 is correct

therefore

The answer is

N 3 and N 4
