There are 7/8 cups of sugar in a canister in the kitchen, Mrs. Johnson use a 1/2 of the sugar when she was preparing dessert for her daughters birthday cake, how much sugar did she use?
To find out how much sugar Mrs. Johnson used, we need to multiply 7/8 by 1/2.
7/8 * 1/2 = (7*1)/(8*2) = 7/16
Therefore, Mrs. Johnson used 7/16 cups of sugar.
To find out how much sugar Mrs. Johnson used, we need to multiply the fraction representing the amount of sugar in the canister by the fraction representing the amount used.
The fraction representing the amount of sugar in the canister is 7/8.
The fraction representing the amount used is 1/2.
To multiply fractions, we multiply the numerators (top numbers) and the denominators (bottom numbers):
(7/8) * (1/2) = (7 * 1) / (8 * 2) = 7/16
Therefore, Mrs. Johnson used 7/16 cups of sugar when preparing the dessert for her daughter's birthday cake.
To find out how much sugar Mrs. Johnson used, we need to subtract 1/2 from 7/8.
To subtract fractions, we need to have a common denominator. The least common denominator (LCD) for 2 and 8 is 8.
Now, let's convert both fractions to have a denominator of 8:
1/2 is equivalent to 4/8.
Now we can subtract:
7/8 - 4/8 = 3/8
Therefore, Mrs. Johnson used 3/8 cups of sugar for the dessert.
How much did Mr. Romanov
Pay for 9.3 gallons of gas at $3.30 a gallon.
To find out how much Mr. Romanov paid for 9.3 gallons of gas at $3.30 per gallon, we need to multiply the number of gallons by the price per gallon.
9.3 gallons * $3.30/gallon = $30.69
Therefore, Mr. Romanov paid $30.69 for 9.3 gallons of gas.
