Serhud [2]

Answer:

Step-by-step explanation:

given $\frac{j^2}{2j}$ × $\frac{2j}{3g}$

the 2j on the denominator of the first fraction cancels with the 2j on the numerator of the second fraction, leaving the expression in simplified form as

= $\frac{j^2}{3g}$ → D

dolphi86 [110]

Answer:

$5 \times \frac{2}{10}$

Step-by-step explanation:

The number of times 10 can go in 52 will be the whole number

$5 \times \frac{?}{?}$

10 will go in 52 5times which will be 50 remainder two.The remainder will be the numerator

$5 \times \frac{2}{?}$

The denominator will be the original denominator (the number below)

$5 \times \frac{2}{10}$

The ratio of the area of ∆ABC to the area of ∆DEF is; 1:100.

<h3>What is the ratio of the area of ∆ABC to the area of ∆DEF?</h3>

Since, a major criterion for similarity and congruence of triangles is that the ratio of corresponding sides are equal.

On this note, since the task content suggest that the ratio of the perimeters is; 1:10, it follows from conventional mathematics that the ratio of their areas is given as; 1²:10²; 1:100.
