Question

simplify 1 upon 4 multiply 2.7 minus 5 upon 14 x 9 x minus 2 upon 3 + 3 accounts a 11 and 12

Answer 1

(1\4×2\7)-(5\14×-2\3)+(3\7×9\2)
(1/14)-(-5/21)+(27/14)
(28/14)+(5/21)
2+(5/21)
(42+5)/21
47/21

Answer 2

Answer:

$(\frac{1}{4}\times\frac{2}{7})-(\frac{5}{14}\times\frac{-2}{3})+(\frac{3}{7}\times\frac{9}{2})=2.23$

Step-by-step explanation:

Given : Expression $(\frac{1}{4}\times\frac{2}{7})-(\frac{5}{14}\times\frac{-2}{3})+(\frac{3}{7}\times\frac{9}{2})$

To find : Simplify the expression?

Solution :

Step 1 - Write the expression

$(\frac{1}{4}\times\frac{2}{7})-(\frac{5}{14}\times\frac{-2}{3})+(\frac{3}{7}\times\frac{9}{2})$

Step 2 - Multiply the inside term parenthesis,

$=\frac{2}{28}+\frac{10}{42}+\frac{27}{14}$

Step 3 - Simplify the fraction,

$=\frac{1}{14}+\frac{5}{21}+\frac{27}{14}$

Step 4 - Taking LCM

$=\frac{21+5\times 14+27\times 21}{14\times 21}$

Step 5 - Solve

$=\frac{21+70+567}{294}$

$=\frac{658}{294}$

$=2.23$

Therefore, $(\frac{1}{4}\times\frac{2}{7})-(\frac{5}{14}\times\frac{-2}{3})+(\frac{3}{7}\times\frac{9}{2})=2.23$
