What is the missing denominator in the addition sentence? 15/28 + 9/?
To find the missing denominator in the addition sentence, we need to find a common denominator for the fractions 15/28 and 9/?.
A common denominator is a number that both denominators can divide evenly into.
One way to find a common denominator is to multiply the two denominators together.
So, the missing denominator in the addition sentence is 28.
Which of the following numbers can replace the missing numerator to make the addition sentence true? 32/57 + ?/57 = 54/57
To find the missing numerator in the addition sentence, we need to subtract the numerator of the first fraction from the numerator of the sum.
So, 54/57 - 32/57 = (54 - 32)/57 = 22/57.
Therefore, the missing numerator that can replace the question mark to make the addition sentence true is 22.
Sarina is mixing paint. If she adds 1/4 gallon blue, 1/4 gallon red, and 1/4 gallon white, how much total paint does she have?
To find the total amount of paint, we need to add the fractions representing the amount of each color.
1/4 gallon blue + 1/4 gallon red + 1/4 gallon white = (1/4 + 1/4 + 1/4) gallon
= 3/4 gallon
So, Sarina has a total of 3/4 gallon of paint.
