Answer:
A
0.1 is -1/10 which is obviously less than -1/7 .
Else we can also know by multiplying by 100
-1/10 *100 = -10
-1/7 *100 = -14.444
Answer:
200 questions
Step-by-step explanation:
Given data
Let the total questions be x
so that
21% of x= 42 questions
let us solve for x
21/100*x= 42
0.21*x= 42
0.21x= 42
Divide both sides by 0.21
x= 42/0.21
x= 200 questions
Hence the questions are 200 questions
