Question

Compare 4:10 and 12:20 using fractions. Which ratio is smaller? How do you know?
is this incorrect?
I will make two models representing 12:20 and 4:10 then I will compare the shaded part in the two models then I look to see which model covers more area so I can find which model covers less space then I answer 4:10 take up less space

Answer 1

Step-by-step explanation:

Given Compare 4:10 and 12:20 using fractions. Which ratio is smaller?

• We need to compare the given ratios that is 4 : 10 and 12 : 20
• So it can be reduced as
• 4/10 = 2/5 and 12/20 = 3/5
• So the fractions are 2/5 and 3/5
• Since the denominators are same we can say that 2 is smaller than 3 and so the fraction 2/5 is smaller
• OR
• Taking lcm of 4/10 and 12/20 we get 20 as lcm
• So 4/10 x 20 = 8
• 12/20 x 20 = 12
• So 8 is smaller than 12 and so the fraction 4/10 is smaller
• Therefore 4:10 is smaller.
