1.375 x 80
1.375
x 80
_________
0000
+11000
_________
110.000
80 marked up by 37.5% is 110.
Answer: 6 x 10^12
Step-by-step explanation:
Move the decimal to the left so there is one non-zero digit number left of the decimal point. This will be the exponent placed on 10
Simple, first find a common denominator, 24.
So,
7/4*6= 42/24
and
5/6*6=30/24
Then just add,
42/24
+
30/24
Making it 72/24.
72/24=3
Thus, your answer is, 3.
