Multiplying numerators and denominators to get the LCD in all fraction denominators

= 38−21×24×2

Then rewriting the equation with the equivalent fractions

= 38−428

With like denominators we can operate on just the numerators

= 3−4 2/8

=−39/ 8

Simplifying the answer

= − 39/8

= − 4 7/8

there are students in a school. This number is 15% more than it was last year. Calculate the number of students last year

ANTONII [103]

Answer: See explanation

Step-by-step explanation:

Your question isn't complete but let's help out by giving some values to the question.

Let's say there are 230 students in a school. This number is 15% more than it was last year. Calculate the number of students last year.

Let the number of students last year be x.

Since there's a 15% increase, this implies that (100% + 15%) = 115% of x equals to 230. This will be:

115% of x = 230

115% × x = 230

115/100 × x = 230

1.15x = 230

x = 230/1.15

x = 200

There were 200 students last year.

Just assign the missing values and use the above method and you'll get your answer.

Step-by-step explanation:

8x+8−3(x+4)−7(2−x)

8x+8−(3x+12)−7(2−x)

8x+8−(3x+12)−(14−7x)

8x+8−3x−12−14+7x

(8x−3x+7x)+(8−12−14)
