QUESTION A

We want to write the decimal 0.7 as a fraction.

We multiply the decimal by multiples of until we get a whole number. We then divide the result by the same product of we used to multiply the decimal.

This implies that,

$0.7=\frac{0.7\times10}{10}$

We simplify the numerator by moving the decimal point forward once to obtain,

$0.7=\frac{7}{10}$

QUESTION B

We want to write the decimal 0.051 as a fraction.

We multiply the decimal by multiples of until we get a whole number. We then divide the result by the same product of we used to multiply the decimal.

This implies that,

$0.051=\frac{0.051\times1000}{1000}$

We simplify the numerator by moving the decimal point forward three times to obtain,

$0.051=\frac{51}{1000}$

QUESTION C

We want to write the decimal 0.473 as a fraction.

We multiply the decimal by multiples of until we get a whole number. We then divide the result by the same product of we used to multiply the decimal.

This implies that,

$0.473=\frac{0.473\times1000}{1000}$

We simplify the numerator by moving the decimal point forward three times to obtain,

$0.473=\frac{473}{1000}$

QUESTION D

We want to write the decimal 0.27 as a fraction.

We multiply the decimal by multiples of until we get a whole number. We then divide the result by the same product of we used to multiply the decimal.

This implies that,

$0.27=\frac{0.27\times100}{100}$

We simplify the numerator by moving the decimal point forward two times to obtain,

$0.27=\frac{27}{100}$

QUESTION E

We want to write the decimal 5.37 as a fraction.

We multiply the decimal by multiples of until we get a whole number. We then divide the result by the same product of we used to multiply the decimal.

This implies that,

$5.37=\frac{5.37\times100}{100}$

We simplify the numerator by moving the decimal point forward two times to obtain,

$5.37=\frac{537}{100}$

We rewrite as a mixed number to obtain,

$5.37=5\frac{37}{100}$

QUESTION F

We want to write the decimal 16.49 as a fraction.

We multiply the decimal by multiples of until we get a whole number. We then divide the result by the same product of we used to multiply the decimal.

This implies that,

$16.49=\frac{16.49\times100}{100}$

We simplify the numerator by moving the decimal point forward two times to obtain,

$16.49=\frac{1649}{100}$

We rewrite as a mixed number to obtain,

$16.49=16\frac{49}{100}$

Answer from: Quest

the answer is d

step-by-step explanation:

Answer from: Quest

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

$\frac{ab}{bc} =\frac{ad}{ab}$

now, we can cross multiply

and we get

$ab\timesab=ad\times bc$

$ab^2=ad\times bc$

so, this could be step to prove it

Seth is using the figure shown below to prove pythagorean theorem using triangle similarity: in the
