You paid $36.20 for a sweater that originally cost $90.50. What percentage of the original price was the sweater on sale for?You
marin [14]

Answer:

32.761 %

Step-by-step explanation:

Percentage is any fraction or ration expressed as a fraction of 100.

Percentage is calculated using formula

If A has to be expressed as percentage of then it can be expressed as

A/B * 100 in percentage form .

For given problem price paid for sweater = $36.20

original price of sweater = $90.50

Problem is to express percentage of price for which sweater was on sale for.

It can be mathematically  expressed as

what is 36.20% of 90.5

percentage of price for which sweater was on sale for = (price paid for sweater/original price of sweater  ) * 100

It can be mathematically  expressed as

what is 36.20% of 90.5

=>  ($36.20/$90.50 )* 100= 32.761.

32.761 % of the original price sweater was on sale for.

For better understanding ,It can also be said that that if the original price of sweater had been $100, then you would have got it at $32.761 .

Nick's dad wanted to measure the length of his backyard and asked Nick to do this with his footsteps. Since it was winter, they
masya89 [10]

Answer:

22.44 meters

Step-by-step explanation:

Solution:

First find LCM(51,68)=204.

So their footsteps coincide every time after Nick's 204÷51 = 4th step and his dad's 204÷68 = 3rd step.

So, in the distance of 204 cm, there will be total 6 footsteps, except in the first 204 cm when their "starting" step is counted.

The total distance will be  67 − 1 (starting step)/6 · 204 = 2244 cm or 22.44m.
