Answer:
80 buckets of red paint
Step-by-step explanation:
Given
The ratio of buckets of yellow paint to buckets of red paint in the store to be 3:4
Total ratio = 3 + 4 = 7
Amount of yellow paint = 60
Required
Amount of red paint.
First get the total amount of paint used.
3/7 * x = 60
x is the total paint used
3x/7 = 60
3x = 7*60
x = 420/3
x = 140 buckets of paint
Amount of red paint = Total - Amount of yellow paint
Amount of red paint = 140 - 60
Amount of red paint = 80
Hence there are 80 buckets of red paint in the store
To know if two fractions are proportionate, we need to cross multiply the fractions, if their cross products are equal, then they are proportionate, if not then they are not proportionate, however we can solve for the number that will make each fraction proportionate to the other.
12/21 = 15/24
cross multiply.
12*24 = 15*21
288 = 315 * not proportionate
because we use the 1st fraction as basis, we need to adjust the 2nd fraction to make it proportionate to the 1st fraction.
12/21 we can multiply the fraction by any number as long as we multiply the number to both numerator and denominator to keep the 2nd fraction in proportion to the first fraction.
