() / () = 0.4 = fraction 4 = fraction 25 = fraction 36
(2) / (5) = 0.4 = 4 / 10 = 10 / 25 = 36 / 90
0.4=4/10=2/5=10/25=36/90
() / 4 = 3 / () = 0.25 = () divided by 36 = ()%
25 = () divided by 36 = ()%
I need to know how to calculate,
Do you know what 0.25 is? It's 25% (25%, solved by the last bracket), which means 25 divided by 100. You should understand this. Then 25 / 100, the numerator and denominator of this fraction, and then divide by 25, which is 1 / 4 (the first bracket), which is one fourth. You understand this, then
-0.5 - (- 3.25) + 2 and 3 / 4 + (- 5 and 1 / 2) = () calculation process
=-0.5+3.25+2.75-5.5
=-0.5-5.5+(3.25+2.75)
=-6+6
=0
4 / 9 * {3 / 4 - (7 / 16-0.25)}
4 / 9 * {3 / 4 - (7 / 16-0.25)} = 4 / 9x [(3 / 4 + 1 / 4) - 7 / 16] = 4 / 9x (1-7 / 16) = 4 / 9x9 / 16 = 0.25
