Answer:

Step-by-step explanation:

-4 is really  -1 * 4

-4² = -1 * 4²

-4² = -1 * 16

-4² = -16

Use parenthesis  to square

(-1 * 4)² = (-4)²

(-4)² = 16

Anthony is 154 cm tall, his brother Gerry is 5/7 as tall as him. How tall is Gerry?
11111nata11111 [884]

The correct answer is 110 cm

Explanation:

Fractions always include two values (one at the top and the other at the bottom) and they represent the proportion of something, for example, 1/2 of an apple means there is only half apple. Now, to calculate how much is 5/7 of 154 centimeters, simply divide the total number into the denominator (bottom number) and then multiply the result by the numerator (top number). This process is shown in detail below:

\frac{5}{7}  -  5 is the numerator and 7 is the denominator

5/7 of 154 cm

154 cm / 7 = 22

22 x 5 = 110 cm
