Question

Subtract the following: (a)7/22- 9/33​

Answer 1

Answer: 1/22

Step-by-step explanation: First let’s convert these into simlar fractions, the way you do this is by timesing the denominator of one number by the numerator and denominator of the other number (the numerator is the top number, the denominator is the bottom number.) Visa versa for the other fraction/number

So 22 x 33 = 726,  and 22 x 9 = 198

So the sum now looks like:

7/22 - 198/726

We must now do the same to the other fraction, so if we get the original denominator from the original fraction the sum looks loke 7/22 - 9/33.

So 33 x 22 = 726 and 33 x 7 = 231.

So now that the sum looks like this:

231/726 - 198/726, we can subtract the numerators (NOT THE DENOMINATORS!!!!)

So 231 - 198 = 33,

So 231/726 - 198/726 = 33/726,

If we can we can simplify the fraction, the highest number that can go into 33 is, well, 33. So try dividing 33 into 33 and 726. They go into both, so we can simplify it. 33/33 = 1, and 726/33 = 22.

So your final answer is 1/22.

Hope this helps.
