Compare 4:10 and 12:20 using fractions. Which ratio is smaller? How do you know?

The given information is expressed in ratio. However, a ratio is basically a fraction. So, 4:10 is just equal to 4/10 or 2/5 in simplified terms. Similarly, 12:20 is just equal to 12/20 or 6/5 in simplified terms. The smaller ratio is 2/5 because the numerator is less than the denominator. So, it follows that the answer is less than 1. The other ratio has a much greater numerator. So, we would expect that that would be greater than 1.

4:10

Step-by-step explanation:

4:10 and 12:20

a ratio is a fraction a fraction is a decimal and a decimal is a percent

so we can rewrite the numbers

4/10 and 12/20

find a common factor we can see that there is a 20 for the denominator. 4/10x2=8/20 and for 12/20 we don't have to do anything

8 is smaller than 12 so 4:10 is the smaller ratio

If you still don't get it think about this way:

4 apples:10 oranges

12 apples: 20 oranges

you can simplify so that 4/10 is 2/5 and 12/20 is 3/5

so 4/10 is smaller

reminder: whatever you do to one side you do to the other :)

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
