1)-25/18+14/27*1 17/26 2)2-16/33:24/55 СРОЧНО ПОМОГИТЕ ПОЖАЛУЙСТА

Answer 1

1) .......... = -25/18 + 119/351 = -737 / 702

2) ......... = 2 - 16/33 × 55/24 (24 та 16 скорочуєм) = 2 - 2/33 × 55/3 = 2 - 2/3 × 5/3 = 2- 10/9 = 8/9

Answer 2

1. To solve the expression -25/18 + 14/27 * 1 17/26, we need to follow the order of operations (PEMDAS/BODMAS). First, we perform the multiplication:

14/27 * 1 17/26 = (14/27) * (43/26) = (14 * 43) / (27 * 26) = 602 / 702.

Next, we perform the addition and subtraction:

-25/18 + 602/702 = (-25 * 39) / (18 * 39) + (602 * 13) / (702 * 13) = -975/702 + 7816/702 = (7816 - 975) / 702 = 6841/702.

Therefore, the value of the expression -25/18 + 14/27 * 1 17/26 is 6841/702.

2. To solve the expression 2 - 16/33 : 24/55, again, we follow the order of operations. First, we perform the division:

16/33 : 24/55 = (16/33) / (24/55) = (16/33) * (55/24) = (16 * 55) / (33 * 24) = 880/792.

Next, we perform the subtraction:

2 - 880/792 = (2 * 792) / 792 - 880/792 = 1584/792 - 880/792 = (1584 - 880) / 792 = 704/792.

Finally, we can simplify the fraction:

704/792 = 88/99.

Therefore, the value of the expression 2 - 16/33 : 24/55 is 88/99.
