To calculate this it is necessary to change ‘ 18 out of 25’ into ‘? out of 100’
So, 18/25 = ?/100
18/25x100 = 72
Mark got 72% on his math test.
We set up a proportion: 5/?= 4/100
Cross multiply: 4*?= 5*100
⇒ ?= 5*100/4= 125
5 is 4% of 125.
Hey!
Let's simplify the expression
sum = +
- The term "sum" is used when adding. Therefore, it is equal to "+".
8 times a number and 2 = 8x + 2
- 8 is equal to 8. The term "times" is used when multiplying. Therefore, it is equal to "×". "A number" is a variable. A variable can be any letter. In this case, I have made it "x", which is commonly used.
That gives you: 8x + 2
