Sedrick is ordering 5 dozen donuts for his grandmother's birthday party. he wnats 1/4 of the donuts to be chocolate sprinkles and 1/3 of the donuts to have carmel frosting with nuts. the rest of the donuts will just have a sugar glaze. the donuts with sugar glaze cost $0.12, and the other donuts cost $0.18 each. how much will sedrick have to pay for all the donuts

The answer will be 1/10. First you will change the denominator to the same number because you can’t mutiply fractions if the denominator is different. 5x2=10 and 2x5=10. So both of the denominator will turn into a 10. Now you’ll have to find the numerator. For the first one, multiply it by 2 because that how much the number need to turn equalvilant for the denominator. 1x2=2. So now you know that the first fraction is 2/10. Then you multiply 1 with 5 which is 5. Now the numbers all have the same denominator. Multiply 2/10 and 5/10 which is 1/10.
