Describe a way to make the arithmetic problem 45% x 680 mentally
lord [1]

Answer:

306.

Step-by-step explanation:

Firstly, we are aware 100% of 680 is obviously 680,

Next, we know half of a 100% is 50% therefore half of 680 is 340.

Then, we know 45% is 5% less than 50%

To find 5% of a number mentally, divide it by 10 as 100÷5=20

680÷20=34

Lastly 50% subtracted by 5%: 340-34=306.

Now we know, 45% of 680 is 306.

You are a member of a darts team and they have won £1750 prize money in a competition. £70 is to be saved for a celebration part
grandymaker [24]
Most of the information's that are required for solving this question is already given in the question. It is important to check them minutely before trying to solve the problem in hand.
Amount of prize money won by the darts team = 1750 pounds
The amount of money that needs to be saved = 70 pounds
Then
Amount of money remaining after savings = (1750 - 70) pounds
                                                                     = 1680 pounds
The number of  team members in the darts team = 14
So
The amount of money
that each members of the darts team gets = 1680/14
                                                                     = 70 pounds
From the above deduction we can easily conclude that each member of the darts teams will get an amount of 70 pounds.
