In a set of base-ten blocks, let 1 flat represents 1 unit.
a. What does 1 long represents?
b. What does 1 cube represents?
c. Represent 1.23 using the blocks with these representations.
(a)
To find:
In a set of base-ten block, 1 long represents.
Answer to Problem 1NT
Solution:
1 long represents
Explanation of Solution
Given:
In a set of base-ten blocks, 1 flat represents 1 unit.
Approach:
Write decimal in form of tenths and hundredths.
Calculation:
There are 10 block/ long in 1 flat.
Hence, 1 long/ block represents 0.1 flat.
(b)
To find:
In a set of base-ten block, 1 cube represents.
Answer to Problem 1NT
Solution:
1 cube represents
Explanation of Solution
Given:
In a set of base-ten blocks, 1 flat represents 1 unit.
Approach:
Write decimal in form of tenths and hundredths.
Calculation:
There are again 10 cubes in 1 long.
By equation (1)
Hence, 1 cube represents 0.01 flat.
(c)
To represent:
The number 1.23 using blocks.
Answer to Problem 1NT
Solution:
The representation of 1.23 is
Explanation of Solution
Given:
In a set of base-ten blocks, 1 flat represents 1 unit.
Approach:
Write decimal in form of tenths and hundredths.
Calculation:
Here
1 long = 0.1 flat
1 cube = 0.01 flat
Here 1 represent 1 flat,
