When multiplying fractions, you multiply the denominators together and the numerators together.
3/8 x 4/9
(4•3)/(8•9)
12/72 = 1/6
1/6 is the final answer.
Plug in -2/4 for R
so -2/4+3/4= 1/4
Answer:
Flip the second number
Step-by-step explanation:
To divide by a fraction, you simply flip it over and multiply
Take # 7 as an example:
5 / becomes 5 X
Of course to make a whole number you put a 1 under it:
5 becomes
Then you multiply straight across (top X top and bottom X Bottom)
Lastly, simplify as needed:
2 /
Make the two a fraction and flip the fraction you are dividing with:
which reduces to 6
To remember the steps use Keep it, Change it, Flip it.
Keep the first number, change from division to multiply, and flip the fraction you were going to divide by.

The rule we use here is
If the font size is too small, then it says (a^b)/(a^c) = a^(b-c)
We subtract the exponents when dividing exponentials like this. The bases must be the same.
So this means the exponents 13 and 3 subtract to get 13-3 = 10
We either have an exponent of "13-3" or an exponent of "10" as an equivalent expression. The base stays at 2 the entire time.
