Question

Si va rog sa ma mai ajutati si la asta:
10/21 ori un intreg si 3/4 minus 11/27

Answer 1

10/21 * 1 intreg 3/4 - 11/27 = 
= 10/21*7/4-11/27 =
= 5/3 *1/2-11/27 =
= 5/6-11/27 =
= 23/54

Answer 2

$\frac{10}{21} *1 \frac{3}{4} - \frac{11}{27} = \frac{10}{21} * \frac{7}{4} - \frac{11}{27} = \frac{90-44}{108} = \frac{46}{108}= \frac{23}{54}$
