Painting is 2 in by 1.5 in. Scale is 1 in:40 cm. What are the dimensions of the original painting?

Answers

Answer:

80 cm by 60 cm

Step-by-step explanation:

To solve this we know that the scale is 1 In: 40 Cm since our painting is already in inches all we have to do is multiply the inches by 40, so 2 inches * 40 is 80 and 1.5 * 40 is 60 and now all we do is turn the units into centimeters and we are done!

Convert the decimal to a percent. 0.007

Answers

To convert a decimal to a percent simply just move the decimal point two places to the right and add the percent sign;
0.007 = 0.7%
Hope that helps:D

Hello There!

"Percent" means "per 100" or "over 100". So, to convert 0.007 to percent we rewrite 0.007 in terms of "per 100" or over 100.

Multiply 0.007 by 100/100. Since 100/100 = 1, we are only multiplying by 1 and not changing the value of our number.

$(0.007)/(1)$ X $(100)/(100)$ = $(0.7)/(100)$

Therefore, we have shown that

0.007 = 0.7%
