Answer:
y geometric mean property,n² = 28 × 7 = 196n = 14.By pythagorean
Step-by-step explanation:
The answer would be 4 1/2
Step 1. Multiply 3/4 by 6/1 to get = 18/4
Step 2. Simplify 18/4 to get 4 1/2
—————————————————————————
How to simplify:
Ex: 18/4
See how many times 4 can go into 18.
「divide 4 and 18」
TIP: Always add a 1 under a single number like 3/4x6 change the 6 to: 6/1
