The capacity of a water tank is 1000 litres. If 7/10 parts of the tank is emptied, how many litres of water are left in the tank
frutty [35]

Answer:

300litres

Step-by-step explanation:

capacity of water tank=1000litres

7/10 parts of tank is emptied,

<h2> method 1</h2>

so, to know the litres of water left in the tank has to be equal to 1000litres-emptied tank

let X to represent water left in the tank

X=1000litres-(7/10*1000litres)

X=1000litres-700litres

X=300litres

hence, litres of water left in the tank =300litres

<h2>method 2</h2>

since, full tank is 10/10 and you know the emptied tank has 7/10. meaning the remaining part of water is

10/10-7/10

3/10 of the tank with water

therefore, 3/10*1000litres

300litres.

A florist has 96 white roses, 72 red roses, and 108 pink roses. If all the roses are used, what is the greatest number possible
natali 33 [55]
<h3>The greatest number possible of  identical bouquets that can be made is 12</h3>

<em><u>Solution:</u></em>

Given that,

A florist has 96 white roses, 72 red roses, and 108 pink roses

All the roses are used, we have to find the greatest number possible of  identical bouquets that can be made

Therefore, we have to find the greatest common factor (GCF) of 96, 72 and 108

<u>GCF of 96, 72 and 108</u>

The factors of 72 are: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72

The factors of 96 are: 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 96

The factors of 108 are: 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108

Then the greatest common factor is 12

Thus, greatest number possible of  identical bouquets that can be made is 12
