You have to find the greatest common factor of each and divide both:
8/64=1/8 (I.e, divide both the numerator and denominator by 8)
4:20=1:5
28/36=7/9
28 to 4=7 to 1
16:48=1:3
The percent increase is 18.18 repeating
Step-by-step explanation:
Based on the given conditions,
Formulate:(100-80)÷80
Calculate the sum or difference:20/80
Cross out the common factor:1/4
Multiply a number to both the numerator and the denominator:1/4×25/25
Write as a single fraction :25/4×25
Calculate the product or quotient :25/100
Rewrite a fraction with denominator equals 100 to a percentage:25%
Answer : 25%
1. p=mv
v=p/m
so the answer B is the correct one
