Anthony bought an 8-foot board. He cut off 3/4 of the board to build a shelf, and gave 1/3 of the rest to his brother for an art project. How many inches was the piece Anthony gave to his brother.

Answers

Answer:

8 inches

Step-by-step explanation:

Anthony bought an 8-foot board. He cut off 3/4 of the board to build a shelf

Step 1

The amount of board he used to build the shelf is calculated as:

= 3/4 of 8 foot board

= 3/4 × 8 foot

= 6 foot board.

Step 2

The amount of board left after building the shelf = The rest =

8 foot - 6 foot

= 2 foot

Step 3

We are told that he gave 1/3 of the rest to his brother for an art project

The amount of board he give his brother for an art project =

1/3 × 2 foot

= 2/3 foot

Step 4

How many inches was the piece Anthony gave to his brother?

We convert 2/3 foot to inches

1 foot = 12 inches

2/3 foot = x inches

Cross Multiply

x inches = 2/3 foot × 12 inches

x inches = 8 inches

Therefore, Anthony gave his brother 8 inches of board.

Estimate 154 divide 7

Answers

Answer:

Step-by-step explanation:

The result of 154 divided by 7 will be 22.

What is the rule of division?

The rules of the division include easy memory tricks that make division calculations easier by generating patterns you may use to deconstruct both simple and complex situations. The guidelines establish requirements that a number must meet in order to neatly divide into another number. While some division rules only require one or two steps to evaluate a number's divisibility, others require two or three steps. Even though some of these formulas are lengthy, division rules help hasten the process of dividing huge numbers.

Remember to continue using the divide, multiply, subtract, and drop-down method for long division problems until all of the dividend's digits have been divided. The solution to the division puzzle is the quotient.

Since the given problem is not a large division. We can solve it by breaking 154 into two parts

______

7 / 154 \ 2 2

---------

1 4

---------

Therefore, 22 will come from dividing 154 by 7.
