Quinton writes this problem: 645 divided by 1100 which expressions represent quinton's problem? select each correct answer. 1100 a) 645 b) 645/1100 c) 645 ÷ 1100 d) 1100 ÷ 645       645 e) 1100 f) 1100/645where the numbers are on top of each other they are a fraction, and where there is a / it is the long division symbol.

Its probaly: B, D, and E

C - 645 ÷ 1100

E - 645 /(over) 1100

F - 1100 )645

Step-by-step explanation:

Use words to show how each division problem is read:

a. 12 ÷ 6    b. 12/6    c. 6)12

For all three division symbols, we say “divided by.” The division in

A is read from left to right: “twelve divided by six.”

The division in B is read from top to bottom: “twelve divided by

six.”

The division in C is written with a division box. We read the number

inside the box first: “twelve divided by six.”

We see that all three problems are read the same. Each problem

shows the same division “twelve divided by six.”

answer: #1 ads up by 8 and i don't know #2

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
