You would round it to 656.70 because the 9 behind the 6 is greater than 5 so it rounds up and makes 6 and 7 and all the numbers behind 6 zero.

Answer:

Hence, the required number is 656.7

Step-by-step explanation:

Consider the provided number.

656.692169912

We need to round the number to the 1 decimal place.

There are 9 digits after the decimal place.

First understand the means of rounding to the 1 decimal place.

The meaning of rounding to the 1 decimal place is Round the number value after the integer number, restricted to one decimal place.

For example: Consider the number 8.14 is rounded to 8.1

The rule of rounding a number is:

If 0, 1, 2, 3, or 4 follow the number, round it down.

If 5, 6, 7, 8, or 9 follow the number, round it up.

Now consider the number  656.692169912  

The number at 2 decimal place was 9, so to round the 1 decimal place round the number up.

Thus round the number  656.692169912  to the 1 decimal place is:

656.7

Hence, the required number is 656.7

A school chorus has 90 sixth-grade students and 75 seventh-grade students. The music director wants to make groups of performers
Vera_Pavlovna [14]

Answer:

a) 15 is the largest number of groups that can be made.

b) There would 6 sixth grade students and 5 seventh grade students in each group.

Step-by-step explanation:

Number of sixth-grade students = 90

Number of seventh-grade students = 75

a) What is the largest number of groups that could be formed?

Since the music director wants to make groups with the same combination of sixth and seventh grade students in each group,

The greatest common factor (GCF) of the number of sixth and seventh grade students would give us the required combination.

Factor of 90 = 2*45 = 2*3*15 = 2*3*3*5

Factor of 75 = 3*25 = 3*5*5

The greatest common factors are 3 and 5

GCF = 3*5 = 15

Therefore, 15 is the largest number of groups that can be made.

b. If that many groups are formed, how many students of each grade level would be in each group?

Sixth grade = 90/15 = 6

Seventh grade = 75/15 = 5

Therefore, there would 6 sixth grade students and 5 seventh grade students in each group.
