Answer:
I assume 1 1 2 is 1 ½ since she only has 12 m of clothes.
Step-by-step explanation:
(12/1 ÷ 1 ½) x 57 = N
12/1 ÷ ³/2 = 12/1 x ⅔ = 24/3 = 8 x 57 = Php456
12 is a whole number so make it an improper fraction which is 12/1.
1 ½ is a mixed number/fraction so make it improper by multiplying denominator (2) to the whole number 1 then add the product to the numerator (1). so it become ³/2
Because you have to know how many 1 ½ m or 3/2m will be made from 12 m cloth, you have to divide. And when you divide, you have to use its reciprocal divisor so 3/2 will be ⅔ then multiply. Hence the 12/1 x ⅔ above.
Then the answer will be multiplied to Php57 to get the money she earned which is Php456.
