The right angle was reduced 15 times and then increased by 700%. How much is the resulting angle?

In the first step, remember that the right angle is 90 degrees. We have to reduce the number 90 by 15 times. The phrase “decrease in” means action – division. Based on this, we must divide the number 90 by the number 15.

90/15 = 6 degrees.

Percentage is one hundredth of a value or number, which is denoted by the% symbol. 1% = 1/100 = 0.01. In order to find the specified percentage of a given number, you need to multiply this number by the number of percent and divide by one hundred. For example: a% of the number b.

b * (a / 100) = b / 1 * a / 100 = b * a / 1 * 100 = ab / 100.

We need to increase the resulting angle of 6 degrees by 700%. Let’s calculate what is equal to 700% of the number 6.

6 * 700/100 = 6/1 * 700/100 = 6 * 700/1 * 100 = 42.

In order to multiply an ordinary fraction by an integer, we performed the following steps:

converted an integer to an ordinary fraction.
the numerator of the first fraction is multiplied by the numerator of the second fraction.
the denominator of the first fraction was multiplied by the denominator of the second fraction.
the first piece was written in the numerator and the second in the denominator.
Let’s calculate what the degree measure of the obtained angle is equal to.

6 + 42 = 48 degrees.

Answer: 48 degrees.
