(1/10-1/12)*(51/4+075) eching

$$( \frac { 1 } { 10 } - \frac { 1 } { 12 } ) \times ( 5 \frac { 1 } { 4 } + 075 )$$

Baholash

$$\frac{7}{80}=0,0875$$

Yechim qadamlari

10 va 12 ning eng kichik umumiy karralisi 60 ga teng. \frac{1}{10} va \frac{1}{12} ni 60 maxraj bilan kasrlarga aylantirib oling.

$$\left(\frac{6}{60}-\frac{5}{60}\right)\left(\frac{5\times 4+1}{4}+0\times 75\right)$$

\frac{6}{60} va \frac{5}{60} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{6-5}{60}\left(\frac{5\times 4+1}{4}+0\times 75\right)$$

1 olish uchun 6 dan 5 ni ayirish.

$$\frac{1}{60}\left(\frac{5\times 4+1}{4}+0\times 75\right)$$

20 hosil qilish uchun 5 va 4 ni ko'paytirish.

$$\frac{1}{60}\left(\frac{20+1}{4}+0\times 75\right)$$

21 olish uchun 20 va 1'ni qo'shing.

$$\frac{1}{60}\left(\frac{21}{4}+0\times 75\right)$$

0 hosil qilish uchun 0 va 75 ni ko'paytirish.

$$\frac{1}{60}\left(\frac{21}{4}+0\right)$$

\frac{21}{4} olish uchun \frac{21}{4} va 0'ni qo'shing.

$$\frac{1}{60}\times \frac{21}{4}$$

Suratni maxrajga va maxrajini suratga ko‘paytirish orqali \frac{1}{60} ni \frac{21}{4} ga ko‘paytiring.

$$\frac{1\times 21}{60\times 4}$$

\frac{1\times 21}{60\times 4} kasridagi ko‘paytirishlarni bajaring.

$$\frac{21}{240}$$

\frac{21}{240} ulushini 3 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$\frac{7}{80}$$

Omil

$$\frac{7}{2 ^ {4} \cdot 5} = 0,0875$$
