hint: divisor is x-2 form, thus you can use syntheric division
Answer: This fraction cannot be turned into a whole number, but can be simplified to 1 3/4 which is also 1.75
Sua matemática seria:10.8 * 3 = 32.4
32.4 + 32.4 + 10.8 + 10.8 = 86.4
86.4 * 130 = 11,232
11,232 - 10,000 = 1,232Você precisará de mais 1,232 tijolos para concluí-lo.
Eu espero que isso ajude :)
