The value of (+12) + (+25) is:
1 +37
2 +13
3 +47
4 -37
Explanation:
+37 As both the digits have equal (+) signs and the operation to be performed is addition, so resultant is (+12) + (+25) = 37

Mark \((\checkmark)\) against the correct answer in the following: \(\frac{-6}{13}-\Big(\frac{-7}{15}\Big)=?\)
1 \(\frac{-181}{195}\)
2 \(\frac{181}{195}\)
3 \(\frac{1}{195}\)
4 \(\frac{-1}{195}\)
Explanation:
\(\frac{1}{195}\) The correct option is (c). \(\frac{-6}{13}-\frac{[-7]}{15}\) LCM of 13 and 15 is 195 \(\frac{-6}{13}-\frac{[-7]}{15}\) \(=\frac{-90+91}{195}\) \(=\frac{1}{195}\)
