Step-by-step explanation:
Take the L.C.M of 2 & 5. It's ' 10 '. Firstly find out the factors of 2 [ i.e 1 × 2 ] and then secondly find out the factors of 5 [ i.e 1 × 5 ]. Now , Note that while finding L.C.M of any numbers, Common numbers & Remaining numbers must be multiplied. In our case , common number = 1 & Remaining numbers are 2 & 5. Multiply them : [ 1 × 2 × 5 = 10 ].

Answer:
Step-by-step explanation:
The first expression has value 12
The second expression has value -6
The third expression has value
4
And finally the forth expression has value 1.14
((13 + 7) = 20
(12+4) = 16
16/ (20 - 16)= 16 / 4
16/4 = 4
Answer:
The integers art 7,8 and 9
Step-by-step explanation:
Let the first of the integers be x. Since they are consecutive, the next would be x + 1 and the last would be x + 2
Now we multiply these integers by 2,3 and 4 respectively.
Thus, we have 2(x) + 3(x+1) + 4(x+2), all these add up to be 74
Opening the brackets we have;
2x + 3x + 3 + 4x + 8 = 74
9x + 11 = 74
9x = 74-11
9x = 63
x = 63/9
x = 7
The integers are thus x = 7, x+ 1 = 7+ 1 = 8 and x + 2 = 7+ 2 = 9
