We can find out how much larger something in scientific notation is compared to something else in scientific notation is by dividing the 10 to the power of x of the respective quantities and then dividing the numbers in front of that value (in this case 7 and 13). After we have both of those quotients, we can multiply them to find the answer. 7/13 is approximately 1/2, and 10^10 / 10^8 is 100. 0.5 * 100 is 50, meaning that the answer is approximately 50.

Answer: Letter C: 11
Step-by-step explanation:5 times 2.2=11
14)NO..... -2x+5y=10.....-2(-3)+5(2)=10.....6+10 is not =10
15)YES......-2x+5y=10....-2(-10)+5(-2)=10.....20-10=10
16)YES......-2x+5y=10.....-2(5)+5(4)=10......-10+20=10
Answer:
2/5 is the smallest fraction. Your welcome.
