Answer:
1. (7+3)/2
2. 6, 3
3. 5/6
4. 500, 4000
Step-by-step explanation:
1. We are adding 7 and 3 so use the plus sign, THEN we divide by 2
Because we are adding first, put parentheses
(7+3)/2
2. Nearest whole means whole number (so basically no decimal)
5.823 --> 6 (because 8 is closer to 10 than 0)
3.147 --> 3 (because 1 is closer to 0)
3. 1/3+1/2
Find a common difference, which is 6
Multiply to get 6
1/3*2= 2/6
1/2*3=3/6
3+2=5/6 (when adding keep denominator the same)
4. There are 100 centimeters in a meter
5*100= 500 centimeters
There are 1000 grams in a kilogram
4*1000= 4000 grams
Hope this helps, lemme know if somethings still unclear!!
Step-by-step explanation:
always remember some basic principles when dealing with percentages :
100% is the whole
1% = 100%/100
n% = n×1% = n×100%/100
therefore, n% of an amount m is n/100 × m.
like 25% = 25/100 × m = 0.25 × m
so, now it should be very easy :
the 25% discount of $80 is
0.25×80
the amount deducted by (= after) the discount is
80 - 0.25×80
which is actually 0.75×80
a markup is added into the total cost incurred by the producer of a good or service in order to cover the costs of doing business and create a profit. so, a markup of 40% is simply again
0.40×80
and the sale price including (= after) the markup is then
80 + 0.40×80
