Answer:
58/9
Step-by-step explanation:
5/3 +43/9
Lets take the L.C.M first
The L.C.M would be 9
Solve the term by taking 9 as L.C.M
=15+43/9
Add the numerator.
=58/9
The answer is 58/9 ....
He is wrong...
2 1/2 + 3 3/5 = 97/20
Simplified, I believe the answer is 4 17/20
For example, evaluate 17*5*20:
Method 1: (17*5)*20 = 85*20 = 1,700.
Method 2: 17*(5*20) = 17*100 = 1,700.
Notice that by first multiplying 5*20 to get 100, the calculation
is easy to do in your head.
You can also use the commutative property to rearrange a question:
5*21*4 = 5*4*21 = 20*21 = 420
