Question

Lexi bought 1 and 2/5 pounds of green grapes and 2 and 3/10 pounds of red grapes grapes are $2.99 a pound did Lexi spend more or less than $12 on grapes

Answer 1

Answer:

Less.

Step-by-step explanation: If you multiple 1 2/5 by $2.99 you would get about $4.19. If you multiple 2 3/10 by $2.99 you would get about $6.88. If you add those together, you would get $11.07, which is less than $12.

Answer 2

Amount of green grapes bought = $1\frac{2}{5}=\frac{7}{5}$ pounds

Amount of red grapes = $2\frac{3}{10}=\frac{23}{10}$ pounds

Let us assume that both the grapes have same price per pound.

Total quantity of grapes = $\frac{7}{5}+\frac{23}{10}$

=$\frac{14+23}{10}=\frac{37}{10}$ = 3.7 pounds

Price of 1 pound of grapes = $2.99

So price of 3.7 pounds = $2.99\times3.7$ =11.063

Price is $11.063

Hence, Lexi spent less than $12.
