```Question 289569
a) First note that x-0.3x=x(1-0.3)=x(0.7)=0.7x or in other words, x-0.3x=0.7x
So the complicated expression (x-0.3x)-0.3(x-0.3x) simplifies to 0.7x-0.3(0.7x). Multiply 0.3 and 0.7 to get 0.21. So we should now have 0.7x-0.21x

# Logarithms
In Mathematics, logarithms are the other way of writing the exponents. A logarithm of a number with a base is equal to another number. A logarithm is just the opposite function of exponentiation. For example, if 102 = 100 then log10 100 = 2.
Hence, we can conclude that,

Add 16/15 and 10/8
1st number: 1 1/15, 2nd number: 1 2/8
16/15 + 10/8 is 139/60.
Steps for adding fractions
1. Find the least common denominator or LCM of the two denominators:
LCM of 15 and 8 is 120
2. For the 1st fraction, since 15 × 8 = 120,
16/15 = 16 × 8/15 × 8 = 128/120
