No, the beaker will not hold all three liquids. The total volume of the liquids that Suki wants to pour into the beaker is 25 milliliters of water + 35 milliliters of oil + 45 milliliters of syrup = 105 milliliters. This is greater than the 100 milliliters capacity of the beaker.
Therefore, the beaker will not be able to hold all three liquids, and Suki will need to adjust the amount of one or more of the liquids in order for them to fit into the beaker.
