A biologist measured one lizard that was 7 3 inches long and a second lizard that was 9 4 inches long. How much longer was the first lizard?

Respuesta :

1.9 INCHES shorter then the 9.4 inch lizard

Answer:

first lizard was 1/12 inches longer than second lizard

Step-by-step explanation:

A biologist measured one lizard that was 7/3 inches long and a second lizard that was 9/4 inches long.

To find the difference in length , we subtract the fractions

[tex]\frac{7}{3}-\frac{9}{4}[/tex]

To subtract fractions, we need to make the denominators same

LCD is 12, multiply the first fraction by 4 and second fraction by 3

[tex]\frac{7}{3}-\frac{9}{4}[/tex]

[tex]\frac{28}{12}-\frac{27}{12}[/tex]

Now subtract the fractions

[tex]\frac{1}{12}[/tex]

first lizard was 1/12 inches longer than second lizard
