Answer:
Step-by-step explanation:
What i would do is turn the first one into an improper fraction
7/5 x 1/4
it's easier to multiply this way
see if you can simplify any of the terms first
7 1
5 4
none of the numbers can be broken down further so we just multiply straight across
7 x 1 is 7
5 times 4 is 20
so the answer would be 7/20
Answer:
the answer is 11,600,000,000,000
Step-by-step explanation:
pemdas
(1.2 x 10 ^13) - (4 x 10 ^11)
10^13 = 10,000,000,000,000 put that in scientific notation to make it simpler do same for 10 ^11
10 x 10^13
(1.2 x 10 x 10^13) - ( 4 x 10 x 10^11)
now solve the first equasion
12,000,000,000,000 - 400,000,000,000
subtract
11,600,000,000,000
15/25 Divididing numerator and denominator by 5 we get:
3 / 5
