Answer:

Molly gets 21, Paige gets 14 and Demi gets 7

Step-by-step explanation:

Total = 42

Ratio = 3:2:1

Total Parts = 3+2+1 = 6

Molly:

=> $\frac{3}{6}*42$

=> 3*7

=> 21 sweets

Paige:

=> $\frac{2}{6}*42$

=> 2*7

=> 14 sweets

Demi:

=> $\frac{1}{6}*42$

=> 7 sweets

Add the ratios: 3+2+1= 6

Divide total treats by total ratio:

42/6 = 7

Now multiply each separate ratio by that:

Molly = 3x7 = 21

Paige = 2x7 = 14

Demi = 1x7 = 7

In the following expression, both AAA and BBB are variables that can take positive values.

The value to increase is keeping A constant and decreasing the value of B

<h3>What are fractions?</h3>

Fractions are written as a ratio of two integers. For instance a.b is a fraction where a and b are integers.

In the fraction a/b, the numerator is and the denominator is b. If the value of the denominator is decreasing the fraction will increase but if the value of the denominator is increasing the fraction will decrease.

Given the expression A + 2/B, the higher the value of B provided such that that A is constant, the higher the expression. Hence the expression that will cause the value to increase is keeping A constant and decreasing the value of B

A marvellous spatuletail is flying at an elevation of 4294 \dfrac294924, start fraction, 2, divided by, 9, end fraction meters.

user100 [1]

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete as what is required is not stated.

However, since it deals with height of different elevations and these heights are represented by fractions, a possible question could be to calculate the difference between both elevations

Represent Marvellous Spatuletail with M and Asian crested ibis with A.

$M = 4\frac{2}{9}$
