Lisa went to the hardware store and bought 12 pieces rope. Each rope was
3

of a meter long. If the rope cost $3.50 a meter, how much did she spend?
if i could get some help with this thatd be great :)

Express a fraction with a slash (/) on the same key as "?", e.g., 3/4.
12 * 3/4 = 12 * .75
12 * .75 * $3.50 = ?
oh lol i didnt think of transferring it to a decimal that makes it a lot easier thanks :)
Of course! I'll be happy to help you with this math problem.
To find out how much Lisa spent, we need to calculate the total length of the rope she bought and then multiply it by the cost per meter.
First, we need to determine the length of each rope. We know that each rope is 3/4 of a meter long. To calculate the total length, we multiply this length by the number of ropes purchased:
Length of each rope: 3/4 of a meter
Number of ropes purchased: 12
Total length = (3/4) * 12
To multiply fractions, we multiply the numerators to get the new numerator and multiply the denominators to get the new denominator. So, (3/4) * 12 = (3 * 12) / (4) = 36/4 = 9 meters.
Now that we know the total length of the rope bought, which is 9 meters, we can calculate the total cost. The cost per meter is given as $3.50, so we multiply the total length by the cost per meter:
Total cost = Total length * Cost per meter
Total cost = 9 * $3.50 = $31.50
Therefore, Lisa spent $31.50 on 12 pieces of rope.
