How do you subtract a integer from another integer without using a number line or counters

1 answer:

8 0

This is how I do it. If it is a negative minus a negative, I combine the two - signs to make it an addition problem. Ex. -3 - -4 makes -3+4. The answer would be one.

If it is a negative plus a negative, keep the sign on the greater number and take away the sign the smaller number. Ex. -7 + (-9). Keep the sign on the 9. -7 - 9. The answer would be -16.

natita [175]

Answer:

given,

selling price (sp)=rs 5 ×30

=rs 150

now, gain %=20%

cost price (cp)=

$\frac{sp \times 100}{100 + gain\%}$

$= \frac{150 \times 100}{100 + 20}$

therefore cp= rs125

now,

again in 2nd case

sp= rs 27×5

therefore sp=rs 135

and cp= rs125

now, sp>cp so,

$gain\% = \frac{sp - cp}{cp} \times 100\%$

or, gain=

$= \frac{135 - 125}{125} \times 100\%$

therefore gain %= 8%.... is answer
