2:7=×:35?
N:18=4:8?
1:4=×:28?​


Sagot :

Answer:

1. N= 4

2.y = 1

3. × = 1

4. N = 9

5. × = 7

Step-by-step explanation:

Hope it helps po

1. 6:8 = 3:n

SOLUTION:

6:8 = 3:n

  • Turn the two ratios into fractions.

[tex]\frac{6}{8} = \frac{3}{n}[/tex]

  • Cross-multiply to find the missing value.

n = (8 × 3) ÷ 6

n = 24 ÷ 6

[tex]\boxed{n = 4}[/tex]

[Note: Just repeat the process above to find the missing value. ]

2. y:10 = 8:80

SOLUTION:

[tex]\frac{y}{10} = \frac{8}{80}[/tex]

y = (10 × 8) ÷ 80

y = 80 ÷ 80

[tex]\boxed{y = 1}[/tex]

3. 2:7 = x:35

SOLUTION:

[tex]\frac{2}{7} = \frac{x}{35}[/tex]

x = (35 × 2) ÷ 70

x = 70 ÷ 70

[tex]\boxed{x = 1}[/tex]

4. n:18 = 4:8

SOLUTION:

[tex]\frac{n}{18} = \frac{4}{8}[/tex]

n = (18 × 4) ÷ 8

n = 72 ÷ 8

[tex]\boxed{n = 9}[/tex]

5. 1:4 = x:28

SOLUTION:

[tex]\frac{1}{4} = \frac{x}{28}[/tex]

n = (28 × 1) ÷ 4

n = 28 ÷ 4

[tex]\boxed{x = 7}[/tex]
