How many groups of 5/6 are in 1

9514 1404 393

  1 1/5

Step-by-step explanation:

We want to find the number of times (5/6) goes into 1, so we divide ...

  1/(5/6) = 1 × 6/5 = 6/5 = 1 1/5

There are 1 1/5 groups of 5/6 in 1.

Another way to look at it

You can consider 1 to be divided into 6 equal part:

  o  o  o  o  o  o

We can group these in groups of 5, so each group is 5/6 of the whole:

 (o  o  o  o  o)  o

What we see is that we have 1 group, and 1/5 of another group.

That is, 1 has 1 1/5 groups of 5/6 in it.

none of the option is correct.

step-by-step explanation:

it says to find which expression equals 9^3 sqrt 10 = ?

9^3 sqrt 10 = 729 sqrt 10.

checking option a. 5 sqrt 10 + 4 sqrt 10

5 sqrt 10 + 4 sqrt 10

= 9 sqrt 10.

checking option b. 5^3 sqrt 10 + 4^3 sqrt 10

5^3 sqrt 10 + 4^3 sqrt 10

= 125 sqrt 10 + 64 sqrt 10

= 189 sqrt 10.

checking option c. 5 sqrt 10 + 4^3 sqrt 10

5 sqrt 10 + 4^3 sqrt 10

= 5 sqrt 10 + 64 sqrt 10

= 69 sqrt 10.

checking option d. 5^3 sqrt 10 + 4 sqrt 10

5^3 sqrt 10 + 4 sqrt 10

= 125 sqrt 10 + 4 sqrt 10

= 129 sqrt 10.

hence, none of the option is correct.
