A reciprocal of the number or a certain expression is the multiplicative inverse of a certain numbers. This means that the numerator of the original number becomes the denominator of the reciprocal and the denominator of the original number becomes the numerator of the reciprocal.

In this item, the numerator is -8b and the denominator is 5b - 6. The reciprocal of the expression will then be equal to,

        R = -(5b - 6) / 8b

What’s the value of 27.43? Write answer in a fraction
Nezavi [6.7K]

Answer:

As an improper fraction: 27 \frac{43}{100}

As a mixed fraction: \frac{2743}{100}

Any number could be expressed as a fraction 27 is \frac{27}{1} and since 0.43 is forty-three hundredths we can express it as \frac{43}{100}.

To find the answer as a mixed fraction we have to put the whole number in the beginning and the fraction in the end. 27 \frac{43}{100}

As an improper fraction we have to add 27 / 1 + 43/100 = \frac{2743}{100}

AnnZ [28]

Answer:

3:2

Step-by-step explanation:

Ewen has 48 white tiles and 16 blue tiles

The cost of each white tile was £2

The cost of each blue tile was £4

Therefore the total cost of 48 white tiles is

= 48×2

= £96

The total cost of 16 blue tiles is

= 16×4

= £64

The ratio of the total cost of the white tiles and blue tile can be calculated by dividing the cost of both tiles by their greatest common factor

The greatest common factor of £96 and £64 is 32

96/32 = 3

64/32= 2

Ratio= 3:2

Hence the ratio of the total cost of the white tiles to the blue tiles is 3:2
