Answer:
1.72386*10^6 km^2
Step-by-step explanation:
When I do math with scientific notation I change both to have the same exponent, then you can just do normal arithmetic. This also includes getting rid of the exponent, which I do here.
1.727*10^6 - 3140
Let's go ahead and get rid of the scientific notation for the first one. So 1.727*10^6 = 1,727,000
So now we have 1,727,000 - 3140 = 1,723,860
Since we started in scientific notation let's go back to it. 1.72386*10^6
Use photomath it'll solve it for you easily and it's always correct work for any kind of math
Answer:
5 1/6 ÷ 4 2/3 = 31/28
3 3/4 ÷ 1 2/8 = 3
4 2/4 ÷ 2 1/4 = 2
5 2/5 ÷ 1 4/5 = 3
4 2/8 ÷ 3 2/4 = 17/4
3 3/9 ÷ 2 4/12 = 10/7
7 1/2 ÷ 3 3/5 = 25/12
6 2/8 ÷ 3 1/3 = 15/8
Explanation:
5 1/6 ÷ 4 2/3 = 31/6 ÷ 14/3 = (31/14) / (6/3) = (31/14) / 2 [when you divide by a certain number you multiply that number by the denominator] = 31/28
5 1/6 ÷ 4 2/3 = 31/6 ÷ 14/3 = 31/6 × 3/14
