1) Multiply the numerators.

Multiply the Denominators

Simplify

2) When working with whole numbers you have to make it improper.

Multiply the denominator by the whole number and whatever you get you to add the numerator with it and that is how you make it improper.

Answer:

19 and 29/32 or 19.90625

Step-by-step explanation:

So the 1st Way: We could simplify it and make them into improper fraction in a way like this:

13/4 * 49/8

We can then just multiply the top row and the bottom row:

13 * 49 = 637

4 * 8 = 32

637/32 = 19 and 29/32

The 2nd Way: We could literally add 6 and 1/8, 3.25 times

(I'm so sorry this is a way lol but I couldn't think of another)

6.125 + 6.125 + 6.125 + 6.125(0.25) = 18.375 + 1.53125 = 19.90625 :P

Solve x (give answer as fractions or integers). 2^x =1/2

Rudik [331]

Answer:

x = -1

Step-by-step explanation:

When an exponent is negative, you have to move it to the denominator (or to the numerator if it's already on the denominator). Since the answer is $\frac{1}{2}$ , you know that the 2 has been raised to the power of 1 (any number to the power of 1 is the same number), so you just make it negative. Hope that helps!
