Question

find the difference:
3 1/10 - 1 7/15

please help

​

Answer 1

Answer:

= [3(3/10)] = (33/10)

= [1(7/15)] = (22/15)

We get,

= (33/10) – (22/15)

LCM of 10, 15 = 30

Now, let us change each of the given fraction into an equivalent fraction having 10 as the denominator.

= [(33/10) × (3/3)] = (99/30)

= [(22/15) × (2/2)] = (44/30)

Then,

= (99/30) – (44/30)

= (99 -44)/30

= (55/30)

= (11/6)

= [1(5/6)]

Answer 2

Answer:

[3(1/10)] = [31/10]

[1(7/15)]= [22/15]

we get,

(31/10) - (22/15)

LCM of 10,15=30

Now, let us change each of the given fraction into an equivalent fraction having 10 as the denominator.

[(31/10)(3/3)] = (93/30)

[(22/15)(2/2)] = (44/30)

Then,

(93/30)-(44/30)

(93-44)/30

(49/30)

1(19/30) is the answer
