There are 715 students enrolled in an English course and 960 students enrolled in a speech course. Construct a ratio comparing students enrolled in an English course to students enrolled in a speech course. Write your answer as a decimal, rounded to the thousandths place

715/960 = 0.745

Step-by-step explanation:

The ratio between two numbers A and B can be written as:

A:B.

In this case, we have 715 students in an English course, and 960 students in a speech course.

Then the ratio is:

715:960

Which means that for 715 units in the English course, we have 960 in the speech course.

Now we could simplify this ratio by dividing both numbers by the same number, for example 5.

715/5 = 143

960/5 = 192.

So our ratio is equivalent to:

143:192.

(for each 143 students in the Engish course, we have 192 in the speech course).

Now, this question actually asks for this:

715/960 = 0.745

(which is already rounded to the thousandths place)

This means that:

The number of students in the English course is 0.745 times the number of students in the speech course.

answer: 60

step-by-step explanation:

1/2a + (2/3×30)   = 50

1/2a + 20 = 50

1/2a = 30

a = 60
