Question

write true or false 1) 16:24 = 20:30 2) 16:24 = 30:20 3) 21 : 6 : : 35 : 10 4) 5.2 : 3.9 : : 3 : 4. find out how it's true or false​

Answer 1

Answer:

1) True

2) False

3) True

4) False

Step-by-step explanation:

1)

$\frac{16 \div 8}{24 \div 8} = \frac{2}{3 } \\ \\ \frac{20 \div 10}{30 \div 10} = \frac{2}{3}$

Therefore,16:24 is equal to 20:30

2)

$\frac{16 \div 8}{24 \div 8} = \frac{2}{3} \\ \\ \frac{30 \div 10}{20 \div 10} = \frac{3}{2}$

Therefore,16:24 is not equal to 30:20

3)

$\frac{21 \div 3}{6 \div 3} = \frac{7}{2} \\ \\ \frac{35 \div 5}{10 \div 5} = \frac{7}{2}$

Therefore, 21:3 is equal to 35:10

3)

$\frac{5.2 \div 1.3}{3.9 \div 1.3} = \frac{4}{3} \\ \\ \frac{3 \div 1}{4 \div 1} = \frac{3}{4}$

Therefore, 5.2:3.9 is not equal to 3:4
