Answer:
45.45
186.36
85.897
75
270.37%
144.74%
Step-by-step explanation:
For questions 1 - 4 we need to multiply the quantitity by 100 and then divide by the porcentage we are asked for:
30 is 66% of what?
[tex]\frac{30*100}{66} =45.45[/tex]
41 is 22% of what?
[tex]\frac{41*100}{22}=186.36[/tex]
67 is 78% of what?
[tex]\frac{67*100}{78} =85.897[/tex]
27 is 36% of what?
[tex]\frac{27*100}{36} =75[/tex]
For questions 5 and 6 we need to multiply the amount that we want to know how much porcentage it is by 100, and then divide by the original quantity.
What percent of 43 is 27?
[tex]\frac{43*100}{27}=270.37[/tex]%
What percent of 55 is 38?
[tex]\frac{55*100}{38} =144.74[/tex]%
