A recipe calls for 11/2 cups sugar. How many cups of sugar are needed to triple the recipe.
3 * (3/2) = 9/2 = 4 1/2 cups
Hi
To find out how many cups of sugar are needed to triple the recipe, we first need to determine the amount of sugar needed for the original recipe.
The original recipe calls for 11/2 cups of sugar. To simplify this fraction, we can convert 11/2 to a mixed number or a whole number with a fraction.
To convert the fraction 11/2 to a mixed number:
Divide the numerator (11) by the denominator (2).
11 ÷ 2 = 5 remainder 1
The quotient becomes the whole number (5), and the remainder becomes the new numerator, so the mixed number is 5 1/2.
This means that the original recipe calls for 5 1/2 cups of sugar.
To triple the recipe, we need to multiply the amount of sugar by 3.
Multiplying 5 1/2 by 3:
Multiply the whole number (5) by 3: 5 x 3 = 15.
Multiply the fraction (1/2) by 3: 1/2 x 3 = 3/2.
Adding the whole number and the fraction:
15 + 3/2
To add these, we need a common denominator. The denominator of 2 in 3/2 can be matched by multiplying 15 by 2 to make it 30/2.
15 + 3/2 = 30/2 + 3/2 = 33/2.
So, to triple the recipe, you would need 33/2 cups of sugar.
