.) Mr. Castro had 7/8 gallons of paint. He used 2/5 of it to paint his bicycle. What part of the paint he had used? 2.) Mother bought 14/15 kilograms of pepper. She 1/3 used of it in cooking adobo for the visitors. What part of the pepper did she use?

Given :

1.) Mr. Castro had 7/8 gallons of paint. He used 2/5 of it to paint his bicycle.

2.) Mother bought 14/15 kilograms of pepper. She 1/3 used of it in cooking adobo for the visitors.

To Find :

1.) What part of the paint he had used?

2.) What part of the pepper did she use?

Solution :

Part of paint used by Mr. Castro, p = 7/8 × 2/5 = 7/20 .

Part of pepper used by mother = 14/15 × 1/3 = 14/45 .

Hence, this is the required solution.

step-by-step explanation:

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
