GuruMulti-step reasoning.
Convince another pupil that 0.25 = 1/4. Show your reasoning.
- 0.25 = 25/100 = 1/4 (divide both top and bottom by 25).
- 0.25 has 25 in it and 4 quarters make 100.
- Because both equal 1/2.
- Because the digits look similar.
Answer: 0.25 = 25/100 = 1/4 (divide both top and bottom by 25).. 0.25 = 25/100. Simplify by dividing both by 25: 1/4.
