B is greater
Work Step by Step
If 150% of A is B, then B is more than one whole part (100%) of A. This means B is greater. For example, let A=100. $150\%(A)=B\longrightarrow$ convert percent to decimal by moving decimal 2 places left $1.5A=B\longrightarrow$ substitute for A $1.5(100)=B\longrightarrow$ multiply $150=B$ $100\lt150$, so B is greater.
