Step-by-step explanation:
Count the number of times you have to move the decimal point to the right until it is to the right of the 1st nonzero number.
a) You have to move the decimal point 11 times until it gets to the right of the 1st nonzero number, which is 7. You then rewrite this number as
The exponent of 10 is a negative number because you moved the decimal point to the right.
b) Similarly, you have to move the point 9 times to the right so the answer is
First calculate the difference between the prices of the shoes
67-52= 15
Next, divide the difference by 52 (the original price)
15/52 = 0.28846
Multiply by 100 to get the percentage (rounded to nearest percent)
0.28846 = 28.8% = 29% rounded
The price of the pair of shoes increased by 29% (rounded).
Hope this helps! :)
