Answer:
a) 7 equal sized pieces of 3/8 pounds
7* 3/8 = 21/8
b) 3 equal sized pieces of 7/8 pounds
3* 7/8 = 21/8
Step-by-step explanation:
Martin has 2 5/8 pounds of ground beef.
2 5/8 = 21/8 pounds = 2.625 pounds
Because 21 is divisible by 3 and 7, we can arrange the ground beef in two configurations
a) 7 equal sized pieces of 3/8 pounds
7* 3/8 = 21/8
b) 3 equal sized pieces of 7/8 pounds
3* 7/8 = 21/8
To answer this question you must make a come factor between the 2 fractions I believe the easiest way to do this is multiply the denominator or bottom number by the other one so 4*5 and 5*4 and what you do to the denominator you must do to the numerator so you would have to do 4*4 and 4*5 for the first fraction to get 16/20 and repeat on the other side 1*5 and 4*5 or 5/20 so the to fractions are 16/20+5/20 then add just the numerators 16+5=21 or 21/20 and simplify to 1/20
For this case we have the following expression:

The first thing you should know for this case, is that by power properties we have:
Every number raised to zero is equal to unity.
We then have to rewrite the expression:
Answer:
The given expression is equal to:
option 4.
