I learned that you have to do \frac{is}{of} or is/of
so what you have to do is ?/102 + 35%/100% cross multiply to get your answer

You can use a calculator and times the number by the percentage as 0. etc
e.g. 35% of 100 = 100 times 0.35 = 35

Alborosie
To answer this question, you can use a factor tree, or the table thing (I forgot what it’s called.)
You divide the number by one of its PRIME factors, until there is only one left. The numbers you divided it by are written as shown.
Hope this helps. :)

There are 45 students in a class. The ratio of boys to girls is 2:3. How many boys are there in the class?
Lena [83]

Answer:

18 boys

Step-by-step explanation:

we add 2 and 3 because they are equal parts:

2+3=5

Then we divide 45 by 5 because we want to find what 1 part equals"

45/5=9

We now do 9*2 to get an answer of:

9*2=18

hope this makes sense!

If EF = 2x-7, FG = 4x-20, and EG = 21, find the values of x, EF, and FG.
Serggg [28]

Given -:

EF = 2X-7

FG = 4X-20

EG = 21

FIND OUT

EF =?

FG = ?

To proof

as given in the question

we have the value of EF = 2X-7 , FG = 4X-20 and EG = 21

Thus we have

EG = EF + FG

21 = 2X-7 + 4X- 20

21 = 6x - 27

48 = 6x

x = 8

Hence proved

Now put this value

EF = 2\times 8 - 7\\EF = 9

Now

FG = 4\times 8 - 20\\FG = 12

Hence proved
