(b) 101.1
(c) 111.1
(d) 190​

Answer 1

Answer:

100 is 111% of 90

Step-by-step explanation:

x is 90% of y or x is 90/100 of y or 9/10 of y

How much of x is y?

Let’s use some numbers: 90 is 90% of 100 9/10 x 100 = 90

x = 90

y = 100

What percent of 90 is 100? = 100/90

100 is 111% of 90

Answer 2

Answer:

as the equation could be

X=90% of Y

Convert percentage into fraction

X=(90/100) of Y

X=(90/100)×Y

Now taking 90/100 from RHS to LHS side

Y=(100/90) of X

so for percentage

(100/90)×100=111.1% so answer is c
