1.) What is 35% of 18?

Question

2.) What percent of 76 is 15.2?
3.) 138 is 75% of what number?

lmfaoo thanks
I said that the last question would be my last one
but this is seriously my last one
since these are the last problems :D

Answer 1

1) 18 x .35 = 6.3 (short way)
Long way: x/18 = 35/100 ( 35 % out of 100% )
then cross multiply and get 100x = 35 x 18
simplify : 100x = 630
isolate x: (divide 100 by each side) and you get 6.30 = ANSWER

2) (same process) ANSWER :20% HOW? 15.2 / 76 = x/100 then cross multiply....

3) 138/x = 75/100 answer = 184

Answer 2

1)
18 x 35%
= 18 x 35/100
= 18 x 7/20
= 126/20
= 6.3

2)
15.2/76 x 100%
= 1520/76 %
= 20%

3)
138 ÷ 75%
= 138 ÷ 75/100
= 138 x 100/75
= 138 x 4/3
= 552/3
= 184

Answer 3

18 x .35 = 6.3
15.2/76 = .20 x 100 = 20 %
138/.75 = 184

Answer 4

1. 35% of 18 is 6.3(18x35=630/100=6.3)

2. 2 (15.2 x 100=1520/760 = 2)

3. 184( 138 x 100= 13800/ 75= 184)

Answer 5

1.35% of 18=35/100*18
=7/20*18
=7/10*9
=6.3
2. 100 => -----
if 138 =>15.2
nw cross multiply,
you will get 100*15.2/138
=1520/138
=11.01
3.100 =>75
-----=>138
again on cross multiplying u will get,
100*138/75=184.

Answer 6

IS/OF = %/100 will solve any percent problem.
After you set up the equivalent fractions, solve for the unknown term by cross-multiplying and dividing by the term with an unknown cross-multiple.
I'm not really writing Greek 8 ) Here's an example:

What percent of 85 is 15?

is(15)/of(85) = %/100
Since 15 and 100 are cross-multiples when you write the fractions the standard way, you multiply them.
15*100 = 1500.
Now divide by 85 to find the unknown percent.
1500/85 = 17 and 11/17%.

Answer 7

To translate, chance "is" to =, change "of" to *, change "what" to x, and change "percent" to /100

1) x=.35*18
2) (x/100)*76=15.2
3) 138=.75*x

solve for x

Answer 8

The first one is 18*7/20
The second one is 15.2/76
The third one is 138*3/4

Answer 9

.18 x 35 = 6.3
