Question

(-5/4)×(+1/2)-(-5/6)=


(-3/5)-(+3/2)÷(-1/4)=


(+4/5-3/2)÷(-2/3)=

(+1/3)×(-5/2+(-5/9)÷(-2/6)=


(2/3)×(-4/3+5/6)=

Answer 1

a) (-5/4)x(+1/2)-(-5/6)
>> -5/8 + 5/6
>> -15 + 20/24
>>>5/24

b) (-3/5) - (+3/2) - (-1/4)
>> -3/5 - 3/2 - (-1/4)
>> - 6 - 15/10 - (-1/4)
>> -21/10 + 1/4
>> -42 + 5/20
>> - 37/20

c) (+4/5 - 3/2) - (-2/3)
>> (+8 - 15/10) - (-2/3)
>> (-7/10) + (2/3)
>> -21 + 20 / 30
>> -1/30

d) (+1/3)x(-5/2+(-5/9)÷(-2/6)
>> (+1/3)x(-5/2-5/9÷(-2/6)
>> (+1/3)x(-45-10/18)÷(-2/6)
>> (-1/3)x(-55/18÷(-2/6)
>> (+1/3)x(-330/-36)
>> -330/-108
>> 330/108 (÷2)
>> 165/54 (÷3)
>> 55/18

e) (2/3)x(-4/3+5/6)
>> (2/3)x(-8+5/6)
>> (2/3)x(-3/6)
>> -6/18 (÷2)
>> -3/9 (÷3)
>> -1/3
