Which fraction is greater? how do you know? a) 2/3 , 2/5​
rusak2 [61]

Answer:

2/3 is greater

Step-by-step explanation:

Two fractions can only be compared if their denominators are equal. In the given problem they are different, so first we make them equal.

\frac{2}{3}  =  \frac{2 \times 5}{3 \times 5}  =  \frac{10}{15}  \\  \\  \frac{2}{5}  =  \frac{2 \times 3}{5 \times 3}  =  \frac{6}{15} \\  \\   \because \: \frac{10}{15} > \frac{6}{15} \\  \\  \purple{ \boxed{ \bold{ \therefore \: \frac{2}{3}   > \frac{2}{5}  }}}

A submarine is positioned at 300 feet below sea level. A bird is flying 100 foot above sea
alexandr1967 [171]

Answer:

h = 400 ft

The bird is 400 ft above the submarine

Step-by-step explanation:

Given;

The submarine is 300 feet below sea level

Vertical distance between submarine and sea level h1 = 300 feet

The bird is flying at 100 feet above sea level

Vertical distance between the sea level and the bird h2 = 100 feet

The total vertical distance between the bird and the submarine is the sum of the vertical distance between submarine and sea level and the vertical distance between the sea level and the bird.

h = h1 + h2

h = 300 ft + 100 ft

h = 400 ft

The bird is 400 ft above the submarine
