Step-by-step explanation:
So basically you separate the numbers like 1 1 1 1 0 1, and time 2 while having the number of numbers as the exponent decreasing. Like this, 1x2^5+1x2^4+1x2^3+1x2^2+0x2^1+1x2^0. Then figure it out and it would be 32+16+8+4+0+1=61. If don't understand, look at the picture below
Step-by-step explanation:
1 kg = 2.2 pounds
0.45 kg = 1 pounds to see whether it's correct or not we can cross multiply the given equations
multiply 1 kg with 1 pounds and 0.45 kg with 2.2 pounds then check if they are equal
1 × 1 = 2.2 × 0.45
1 = 0.99 as you can see this is not an equality therefore the statement is wrong.
