James bought 1 1/8 kg of beef. He used 3/4 of it to make some beef patties. How much beef had he left
To solve the problem, we need to find out how much beef James used and subtract that amount from the total amount he bought.
James used 3/4 of 1 1/8 kg of beef to make patties. We can first convert 1 1/8 to an improper fraction:
1 1/8 = 9/8
Now we can multiply 9/8 by 3/4 to find out how much beef James used:
9/8 x 3/4 = 27/32
So James used 27/32 kg of beef to make patties.
To find out how much beef he had left, we can subtract 27/32 from the original amount he bought (which was 1 1/8 or 9/8):
9/8 - 27/32 = 36/32 - 27/32 = 9/32
Therefore, James had 9/32 kg of beef left after making patties.
To find out how much beef James had left, we need to subtract the amount of beef he used to make the beef patties from the total amount of beef he bought.
James bought 1 1/8 kg of beef, which can also be written as 9/8 kg.
He used 3/4 of it to make the beef patties.
To find out how much beef he used, we need to multiply the total amount of beef by the fraction used.
(9/8 kg) * (3/4) = (9 * 3) / (8 * 4) = 27/32 kg.
Therefore, James used 27/32 kg of beef to make the beef patties.
To find out how much he had left, we need to subtract the amount used from the total amount bought.
(9/8 kg) - (27/32 kg) = (9/8 kg) - (27/32 kg) = (72/64 kg) - (27/32 kg) = (72 - 27) / 64 kg = 45/64 kg.
Therefore, James had 45/64 kg of beef left.
