Income Taxes	9 Months Ended
	Jan. 31, 2020
Income Tax Disclosure [Abstract]
Income Taxes	The effective tax rates for the three months ended January 31, 2020 and 2019, were 22.7 and 22.8 percent, respectively, and for the nine months ended January 31, 2020 and 2019, were 24.0 and 26.1 percent, respectively. During the three and nine months ended January 31, 2020 and 2019, the effective tax rates varied from the U.S. statutory income tax rate of 21.0 percent primarily due to the impact of state income taxes. The effective tax rate for the nine months ended January 31, 2019, was also unfavorably impacted by additional income tax expense related to the sale of the U.S. baking business. Within the next 12 months, it is reasonably possible that we could decrease our unrecognized tax benefits by an additional $2.6, primarily as a result of expiring statute of limitations periods. As of January 31, 2020, the undistributed earnings of our foreign subsidiaries remain permanently reinvested.
