24 can go 3 times into 84
Answer:
x(x + 5) = 0
Step-by-step explanation:
x² = - 5x
x² + 5x = 0
<em><u>x(x + 5) = 0</u></em>

Step 1: LCM of 24 , 30 and 60 = 120
so 120 is the least no which is divisible by all 24 , 30 and 60
Step 2: factors of 120 will be 2^3 * 3 * 5
so the least perfect square, which is divisible by 24, 30 and 60 will be
(2^3 * 3 * 5) x ( 2 * 3 * 5 ) = 3600
3600
<u> 70</u> =<u>63</u><u>
</u>100 ?
cross multiply 63 and 100= 6300 then divide by 70= 90
