Answer:

1. 15 : 20 = 5 : 6

15 × 6 = 90

20 × 5 = 100

Answer : No

2. 5 : 2 = 3 : 4

5 × 4 = 20

2 × 3 = 6

Answer : No

3. 1 : 2 = 4 : 8

1 × 8 = 8

2 × 4 = 8

Answer : Yes

Answer:

1. NO

2. NO

3. YES

Step-by-step explanation:

Number 1;

Given: 15/20 = 5/6

Solution:

[tex]\frac{15 x 6}{20 x 6} = \frac{5x20}{6 x 20}[/tex] multiply

[tex]\frac{90}{120} =\frac{100}{120}[/tex] compare the numerators since the denominators are the same
[tex]90 = 100[/tex]   X FALSE

Number 2;

Given: 5/2 = 3/4

Solution:

[tex]\frac{5x4}{2x4} = \frac{3x2}{4x2}[/tex] multiply

[tex]\frac{20}{8} =\frac{6}{8}[/tex] compare the numerators since the denominators are the same

[tex]20 = 6[/tex] X FALSE

Number 3;

Given: 1/2 = 4/8 ​

Solution:

[tex]\frac{1x8}{2x8} =\frac{4x2}{8x2}[/tex] multiply

[tex]\frac{8}{16} =\frac{8}{16}[/tex] compare the numerators since the denominators are the same

[tex]8 = 8[/tex]  ✓ TRUE
