Answer:
1. 4.57 x 10 raised to negative 4
*move the decimal point to the right 4 times
*that must be this after you move the decimal point: 00004.57
2. 0.004
* if the exponent is negative, then it is decimal.
* the exponent is the number of zeros like 3: 000
* next put the coefficient 2.4 right to the zeros (remove decimal point)
* then move the decimal point 3 times to the left
*and this represents: 0.0024
3. 10
* 10 is always the base
4. 17/5
* there are fruits of any kind and apple is one of it
* try to divide these two numbers, the total is 3.4
* therefore you can say that 17/5 is the answer
5. 0.66666 and 49 is irrational
6. left side of negative 6
* try to use a number line then draw these givens.
7. left side of a percent (1.00)
* 0 is < a percent
* because 1/4 is is 25-hundredths
* and zero is just zero
8. 3 and 4
* change the mixed to a fraction -> 17/5
* then find the quotient -> 17/5 = 3.4
* therefore 3 2/5 is between 3 and 4
9.
10. -7 and 8
* just changed it to improper
* then divide it and if it lies to a number like 7, then it is 7
11. 5.2 x 10 raised to 6
* take the 52 as the coefficient and write a decimal point on the center
* count the zeros and that will be the exponent of the base 10
* then that's it = 5.2 x 10 raised to 6
12. 1.001 x 10 raised to positive 3
* take it whole and put a decimal point right to the number -> 1.001
* then count the digit starting from the decimal point to the right
* then apply it -> 1.001 x 10 raised to positive 3
13. 14.50 pesos
* take the 8 from the mixed and determine that it is 10 pesos
* then convert kilometers left (4 1/2) to a fraction -> 9/2
* next divide it -> 9/2 = 4.50
* then add 10 and 4.50 = 14.50
* therefore, you will pay 14.50 pesos for his service.
14. 7/5
* add 3/5 and 4/5 = 7/5
15. 26.25 pesos
* subtract her allowance and how much he will spend on food
* 50 - 23.75 = 26.25
+ The total of her saving is 26.25 pesos.
On the Performance Task, you now can answer the other problems on the tasks independently. Just see how I answered the other questions above and use the given method that the task assigned. I hope you've now understood how to answer and get rid of solving these easy questions.
My advice to you, try to solve difficult problems and take them as a challenge. You will notice that after solving many problems, it will be so easy and will be just a piece of cake. You're far beyond my stand, try my advice and become a master, not Jack whose a master of all trades, master of none. Good Luck!
