Answer:
80 cm as a fraction of 4 m is
Step-by-step explanation:
To write the fraction of two different quantities you must put them in the same units
<u><em>Example:</em></u> To write 5 grams as a fraction of 1 kilogram
- Change the 1 kilogram to grams by multiplying it by 1000
- The fraction will be
- Reduce it to its simplest form by divide up and down by 5 to be
<em>Let us use the same way to solve the question</em>
∵ 1 meter = 100 centimeters
∴ 4 meters = 4 × 100 = 400 centimeters
→ Now put 80 centimeters as a numerator and 400 centimeters as
a denominator
∵ The fraction is
→ Divide up and down by 80 to simplify it
∴ The fraction =
∵ 80 ÷ 80 = 1
∵ 400 ÷ 80 = 5
∴ The fraction in its simplest form =
∴ 80 cm as a fraction of 4 m is
