Question

A large bag or sugar weighs 7 1/2 lb. Gow Much does 1 1/4 bags of sugar weighs

Answer 1

(3)

`9(3)/(8)lb`

(4)

6÷
`(1)/(5)`=
`30`

Explanation:

(5)

we are given

1 bag of sugar is

`=7(1)/(2)lb=(2* 7+1)/(2)lb=(15)/(2)lb`

we have to find weigh of 1 1/4 bags of sugar

we can multiply both sides by 1 1/4

`1(1)/(4)` bags of sugar

`=1(1)/(4)* (15)/(2)lb`

`=(5)/(4)* (15)/(2)lb`

`=(75)/(8)lb`

we can write in mixed form

`=9(3)/(8)lb`

(4)

we are given

6÷
`(1)/(5)`

we know that

a÷
`(b)/(c)`=
`(a* c)/(b)`

now, we can use formula

6÷
`(1)/(5)`=
`(6* 5)/(1)`

6÷
`(1)/(5)`=
`30`

Answer 2

The correct option is 4.

Step-by-step explanation:

It is given that the weight of a large bag of sugar is
`7(1)/(2)`. This complex fraction can be written as

`7(1)/(2)=(14+1)/(2)=(15)/(2)`

So, the weight of a large bag of sugar is
`(15)/(2)`.

The number of bags is
`1(1)/(4)`. It means the number of bags is number of bags is
`(5)/(4)`.

`1\text{ Bag}=(15)/(2)\text{ lb}`

Multiply both side by
`(5)/(4)`.

`1* (5)/(4)\text{ Bag}=(15)/(2)* (5)/(4)\text{ lb}`

`(5)/(4)\text{ Bag}=(75)/(8)\text{ lb}`

`(5)/(4)\text{ Bag}=9(3)/(8)\text{ lb}`

Therefore correct option is 4.
