So for the tenth figure you would have 58 toothpicks on the bottom layer and then because for all the layers above you wouldn't need a base, you would just find the number in the next row and from there keep subtracting 4:
58
35
31
27
23
19
15
11
7

How to change 7/10 to a percent
Ulleksa [173]

Answer:

70%

Step-by-step explanation:

since 7/10 is 0.7 as a decimal

you can then turn it into a percent by moving the decimal point two spots to the right

70 --> 70%

another way to do it is, to add zeros on both the numerator and denominator

then it is valued at 70/100

a percent is a number over 100

70 ---> 70%

your answer is 70%

hope this helps
