Issolvi A=(15/4-5/2)*7/5

$$A = ( \frac { 15 } { 4 } - \frac { 5 } { 2 } ) \times \frac { 7 } { 5 }$$

Solvi għal A

$$A = \frac{7}{4} = 1\frac{3}{4} = 1.75$$

Passi biex Issolvi l-Ekwazzjoni Lineari

L-inqas multipli komuni ta' 4 u 2 huwa 4. Ikkonverti \frac{15}{4} u \frac{5}{2} fi frazzjonijiet bid-denominatur 4.

$$A=\left(\frac{15}{4}-\frac{10}{4}\right)\times \frac{7}{5}$$

Billi \frac{15}{4} u \frac{10}{4} għandhom l-istess denominatur, naqqashom billi tnaqqas in-numeraturi tagħhom.

$$A=\frac{15-10}{4}\times \frac{7}{5}$$

Naqqas 10 minn 15 biex tikseb 5.

$$A=\frac{5}{4}\times \frac{7}{5}$$

Immultiplika \frac{5}{4} b'\frac{7}{5} billi timmultiplika n-numeratur bin-numeratur u d-denominatur bid-denominatur.

$$A=\frac{5\times 7}{4\times 5}$$

Annulla 5 fin-numeratur u d-denominatur.

$$A=\frac{7}{4}$$

Assenja A

$$A≔\frac{7}{4}$$
