Answer:

-12

Step-by-step explanation:

rewrite the problem. Remember that two minus signs negate each other and become a plus sign and minus signs override plus signs:

-2.5-7.4+1.2-3.9+0.6 = -12

Answer:

-12

Step-by-step explanation:

−2.5+(−7.4)−(−1.2)−(+3.9)+(+0.6)

Subtracting a negative is adding

−2.5+(−7.4)+(1.2)−(+3.9)+(+0.6)

Combine like terms

-9.9 +(1.2)−(+3.9)+(+0.6)

-8.7-3.9+.6

-12.6+.6

-12

Barnika bought 100 eggs for Rs. 900. Out
Helga [31]

Step-by-step explanation:

cost of an egg= 900/100= Rs.9

Total cost = 100×9=Rs.900

when 8 eggs broken, the eggs remained to sell is 92(100-8)

Total sales = 10.50×92=Rs.966

profit = total cost-total sales

profit =966-900= Rs.66

profit percentage =profit/total sales×100%

66/966×100%=6.832%

What fraction is less than 1/2. 3/4,1/6,6/12,4/10,5/8,5/2
vazorg [7]
1/6! Any fraction that represents less than a half of a whole is less than 1/2. You could also convert them to the same denominator and see the difference. Make sure whatever you do to the first fraction, you do to the other!
