Step-by-step explanation:
Step 1. Multiply the bottom number of the fraction by the whole number
Step 2. Simplify the fraction (if needed)
Example:
1 ÷ 3
-
2
Step 1. Multiply the bottom number of the fraction by the whole number:
1
--------
2 x 3
Which equals:
1
--
16
Step 2. Fraction is already as simple as possible, so no need for step 2.
Answer:
1
- ÷ 3 = 1
2 --
6
(2x-5)(3x-1)=0
2x-5 = 0 or 3x-1= 0
2x = 5 3x = 1
x = 5/2 x = 1/3
Answer: x=5/2; x=1/3
First, you can add up 4+2 to get 6 because they’re both rates.
Next, divide 18 by 6 and you get 3.
So, it will take three hours for the boys to meet up.
One way to check your answer is to multiply 4x3=12 and 2x3=6 and 12+6 is 18.
Answer:
10 : 3
Step-by-step explanation:
Convert one of the measurements so that it is in the same form as the other. (Easiest to convert m to cms so we are not working with decimals)
2.5 m = 2.5 x 100 = 250 cm (since there are 100 cm in a meter)
Therefore, as a ratio:
250 : 75
We can divide both by 5:
50 : 15
We can further divide by 5:
10 : 3
(no further simplifying)
So 2.5 m to 75cm as a ratio is 10 : 3
