3.725 kilograms or ¹/₄ part
Further explanation
Given:
An artist builds a sculpture out of metal and wood that weighs 14.9 kilograms.
- ³/₄ of this weight is metal, and
- the rest is wood.
Question:
How much does the wood part of the sculpture weighs?
The Process:
From the information above, we make a diagram that matches the composition of the sculpture material.
[tex]\boxed{metal}\boxed{metal}\boxed{metal}\boxed{wood} = 14.9 \ kilograms[/tex]
- ³/₄ of this weight is metal, and
- the rest is wood, which is [tex]\boxed{ \ 1 - \frac{3}{4} = \frac{1}{4} \ }[/tex].
And now, let us calculate the wood part of the sculpture weighs.
[tex]\boxed{ \ = \frac{1}{4} \times 14.9 \ kilograms \ }[/tex]
Both 4 and 14.9 are multiplied by 10.
[tex]\boxed{ \ = \frac{1}{40} \times 149 \ kilograms \ }[/tex]
[tex]\boxed{ \ = \frac{149}{40} \ kilograms \ }[/tex]
Both the numerator and denominator are divided by 4.
[tex]\boxed{ \ = \frac{37.25}{10} \ kilograms \ }[/tex]
[tex]\boxed{ \ = \frac{3,725}{1,000} \ kilograms \ }[/tex]
[tex]\boxed{\boxed{ \ 3.725 \ kilograms \ }}[/tex]
Thus, the wood part of the sculpture weighs is 3.725 kilograms or ¹/₄ part.
