We have two ways to do this, pick your favor:
either by fractions:
÷ 
(
Multiply by the reciprocal of which is 2(flip it)
× 2 = 
= 1.25
Or change them to decimals:
= 0.5
0.625 ÷ 0.5
0.5 I 0.625
multiply by 10 to make it easier to divide(it still gives us the same answer)
0.5 × 10 = 5
0.625 × 10 = 6.25

Similar triangles may or may not have equal side lengths
Triangles ABC and DEF are similar by SSS theorem
<h3>How to determine the similarity statement</h3>The coordinates of the two triangles are:
A (0,0), B (4,0), C (0,2), D (0,0), E (2,0), and F (0,1)
Calculate the lengths of both triangles using the following distance formula
For triangle ABC, we have:
For triangle DEF, we have:
Divide corresponding sides of the triangles to calculate the scale factor k
This gives
Evaluate the quotients
Since the quotients are equal, then the triangles are similar
Hence, triangles ABC and DEF are similar by SSS theorem

Answer:
(a). 15
(b). 78
Step-by-step explanation:
Growth of the population of a fruit fly is modeled by
N(t) =
where t = number of days from the beginning of the experiment.
(a). For t = 0 [Initial population]
N(0) =
=
=
= 15
Initial population of the fruit flies were 15.
(b).Population of the fruit fly colony on 11th day.
N(11) =
=
=
=
=
= 77.82
≈ 78
On 11th day number of fruit flies colony were 78.
